That is a great question. My first thought would be that the lower frequency supplied the resonant pattern for the distribution while the higher frequncy secondary wave suplies the kinetic energy to hold the oobleck in place as more gathers.

The tanks is open for very little time pretty much to get in and out. The human body has a surface temperature of about 93F so it does not draw heat from the water.After using it might lose a little heat but not much. With insulation it should stay at 93F once you get it there with the water bed heater maintaining the temperature.Thanks for asking questions!

It is all about low and slow. It took a couple days to get the water up to 93F but with a closed lid and the insulation I ended up adding later it gets up to 93 and stays there.

I will get that changed. It is good to be accurate! Thanks for letting me know.

Thanks for taking the time to give such a detailed answer to the question!

That is a good question. It does not predict the weather as far as I can tell. But it is a really fun project that looks cool as it changes.

That would be great to see! Let me know if you end up working on it and if there are any questions!

Hello! That is interesting that you would ask. I have another instructable that looks at different concentrations here: https://www.instructables.com/2-Storm-Glass-Guide/The lower the lower the concentration of the camphor the lower the crystallization temperature so if you are wanting the cyrstals to form at a higher temperature than a larger amount of camphor should be used. Thanks for asking!

That is really interesting to learn! Thanks for sharing the knowledge. All that I had know about camphor was that the box said not to ingest it and that it was used to help prevent rusting on tools.It is always great to learn new things.

I had been wondering about that but did not get past thinking about it to research the proper way. Thanks for the reminder for best practices in making aokutions like this.

It is important to have it near a window where it experiences some good temperature swings such as cold at night and then warm in the sun during the day.If you make this once the camphor is in the vodka please do not drink it. I am pretty sure camphor is toxic to ingest.

Hello WilkoL! Thanks for asking a question. Yes that would work really well. I would recommend diluting it 50/50 with distilled water and you should be good to go.Let me know how it works!

I drink my coffee coffee to fast to predict the weather unless it is telling me a drought is coming.

This is an amazing build! Thanks for posting. It is providing a lot of helpful insights for making a slightly different telescope design myself!

No TV News coverage yet. Sometimes I do wonder about the weather report during this filming it ranged from in the 70's to a few inches of snow.

Hello ElectroFrank, those are some interesting ideas. I am working on a next generation that is more comfortable and tracks you head better. I had not thought about having it draw from the top of the head. It might be a little bit hardware due to the extra distance from the mouth. I am excited to think about your suggestions!

Let me give it a read and I will try to send you a message with some thoughts.I am honored that you would ask.

Group brainstorming i like it! I can finally look like inspector gadget!

I think you are on to something here.I have been wanting to make a tur-duc-ken ph-ail and I would need something to cut it.It would be a turkey stuffed with a duck stuffed with a chicken stuffed with a pheasant stuffed with a quail.A chainsaw sounds just the right speed.

Yeah. It was crazy. When I used the same fan for my mask project is was starting vertical takeoff.https://www.instructables.com/Take-Your-Breath-Away-Mask-DIY/

That could really through some air. I would not want that clsoe to my head even less than the ducted fan.

Hello Jeanniel1! Thanks for commenting. That is a good question. Having some of the air go upward to keep the umbrella itself dry would be a good idea.

Hey ArduinoPI! Thanks for checking out the instructable and commenting. I will have to look into how they structure their fan to see if there could be improvements there.I have been thinking about different uses for the type of technology that Dyson uses. An example is making a bladeless fan (https://www.instructables.com/Worlds-Largest-Blade...Trying to find ways to use the technology that Dyson does is somethign that has been very fun.

I was curious that since you have 3 separate power banks that will each need their own charging circuitry dropping to different charging voltages that the charging process in this case might be less efficient than a single bank configuration. I am also thinking about the blocking voltage of the MOSFETs and limitations of the body diodes. Not a complete thought yet so I will have to think more before I post again.

What you gain in discharge efficiency is it lost in charging efficiency?

This could be really interested since the distance on the cam between the cam pivot and the can and also between the drill and the end of the cam you could add a belt system that could coordinate flipping the can in time with the cam cycling. That could be really fun.

Wow! Thank you!

Two Question.1. What material is the adapter because that it a great idea that I would like to use sometime and I am wondering if you went with a harder material to handle the strain.2. What sort of laser cutter did you use to cut a 15mm board so cleanly?Also what is your theory about why your ESC died?

How consistently does it dispense the sanitizer through the whole bottle? It is really fun that you are effectively making an aerosol hand sanitizer setup since you are using positive air pressure to push the material up the tube. How rigid is the bottle does it bulge at all during the dispensing?

What an interesting idea, but like you said what has two thumbs to shake a paint can himself? This guy! Did you test a vertical configuration? This would have the linear bearing on a pivot and the paint can attached the shaft on the cam?

This is really interesting. I would think that this could be an interesting non-optical element to a security system where you have accepted MAC addresses could trigger different practical features in a space and then if an unknown address is present and moves around a space it could send a notification.Since it is just sniffing the WiFi what power state can the device be in? How low can the power consumption be?I am going to have to build this myself to play around with it!

Where do you think the inefficiency comes from? Is it because there is a minimum usable pressure that is needed in the tank? Because the mechanical aspects of the drive train do not look that different from a standard bike in that you are peddling into a geared compressor and the the tank powers a geared compressed air engine so right there I could see it dropping to around 80% but 3% seems abysmal.

That is a great idea. You and I are on a very similiar wavelength of thought. the next generation will be positioned to track the nose and mouth like you had just talked about. This has the added benefit or reducign the distance distance between the intake and my mouht and nose and keeping the distance consistent.

Hey RaspberryPiDude314159! Thanks for commenting! I am going to start working on a second generation that will be more effective with better testing and demonstration methods. The goal will be to demonstrate this idea to be more effective than existing mask tech because there is no training needed to achieve a perfect seal on a person's face and there is no moisture saturated surface to touch like a standard mask so the droplets do not transfer to a persons hands. My thoughts have been. It is 2020 we have to be able to have a more advanced and more human solution than putting a piece of clothe over our faces. It was the response to the 1918 Spanish flu so I wanted to ask the question if we could come with a better solution now 100 years later.

Interesting. I have read a little bit about these sensors and how the electrodes suffer from corrosion but I imagine the getting the electronics wet would result in a bigger problem much sooner. I will have to look at the probes that are available maybe if the electronics were recesssed into the base with the probes coming through a gasket or if the electrodes could be on leads to let keep the electronics safe.

What an interesting idea. Does it work similarly if you were to recess the electrode connected to the sponge so that you could elminate the standoffs on the edge of the sponge. This might reduce sensitivity to pressure on the edges of the sponge though.

Have you looked into a peristaltic pump? This could help with flow control and also make it easy to dispense gel based sanitizers.

Are you using a pot that has a drain hole in the bottom? It could be interesting to feed the moisture sensor through the drain hole in the bottom of a pot so that you could have the whole system integrated into the base plate. This could then be augmented by having some plates in the drain pan that are testing for conductivity that would indicate if the drain pan has standing water to let you know if the plant has been over watered and the drain pan is about to overflow

Hello Steven!Thanks for checking out my instructable and commenting. I was in the same boat as you are wanting to have a reason to make and then finally just breaking down and doing it. I am still looking for more projects that would use it but in a more practical way that utilizes its non-newtonian characteristics to benefit from something being harder when under strain and softer when in relaxation.I really liked your epoxy river table. I am reading through it a few times to learn how to use epoxy and live edge for an upcoming project!

Thanks for the advice. This is the first project that I have done with 3D printing so there has been a lot to learn. I will get the STL files up on the instructable shortly!

Hello Mr. Ham!I completely agree the sounds while operating the Chladni plate were unpleasant. I ended up wearing hearing protection to reduce how much it bothered me.It sounds like you and me have been thinking about a very similar solution to how to use a Chladni plate for extended periods of time without it creating too much bothersome noise. In addition to insulation for knocking the sound down I had been thinking about how effective active noise cancellation would be since the acoustics of the chamber would be known and the precise frequency and positioning of the plate and the canceling source to result in some pretty effective destructive interference.I had not thought about trying epoxy to create a permanent shape. I will have to look into what that would take. Thanks for the idea…

Hello Mr Ham!!! (I really like your user name)It was pleasantly surprised how much I enjoyed operating the Chladni plate. The next thing that I am interested in trying is to create a moving sculpture table that uses a chladni plate. The challenge will be to make the system quiet enough.

There is a no need to be so down on your idea. We all have ideas that do not work the first time or even ideas that might never work but it takes effort the think about them and try to follow through on them and courage to share them so that really impressed me from the very begining.Thanks for having the courage the share your ideas! I look forward to hearing more of your ideas

Hello Jeanniel1! Thanks for you positive comment! I imagine the inside of the fog tube and the fire tube act similarly but you are right the moment it exits the tube they are very different.I am working on finishing up a collection of cymatic projects that I am hoping to post soon where I take some of these demonstrations from one dimension to two dimensions. Also it has been really hot where I am so thinking about an ice related project soon too. Thanks for stopping by!

Hello FarrahHosein! Thanks for commenting!I will need to look into how sound impacts water vapor to be able to move forward on the idea that you put forth in your comment. The manipulation of the fog in this project is a function of standing waves of sound. I would think that the first steps would be to start experimenting at ground level in a location that frequently experiences heavy fog to determine if you could dissipate the fog by actively driving speakers that are facing each other.

Hello Vedant04,Thanks for the project idea!Just trying to understand the suggestion a little bit better. I am thinking that I would be pumping fog into this glass box? Then the fan would draw the fog through the box in a vortex and the LEDs would illuminate that vortex?

Hello PhysicsPerson123!Thanks for the comment. I am glad I was able to reduce the sound of the resonant tone in the video since I really did end up using ear muffs for some of the testing and that was coming through in the audio track to make the video a little bit more easy listening!

Hello slangston6241! Thanks for the comment. How are you thinking about trying it?

Hello Jeannie1!Thank you for the fun and kind comment. I will have to look up that art installation that you are talking about because maybe it could inspire another project.Taping things is very much easier than welding but I think after prototyping the concept will be looking to try and make something out of more rigid material.It was really fun to see how the sine wave would run so well even around the bends in the tube sort of like acoustic refraction inside the tube.

Hello RemcoK4,It is really wild what has been discovered in the past that we never hear about! I am very happy that I did not explode. I think that since there was positive gas pressure in the tube pushing the propane out the fire flared out of the tube and did not go into the tube which is where the risk of explosion would be. That is why it is important to wait until there is enough positve pressure in the tube. When you play music the tube causes the fire to jump and dance but it does not create the same effect because most music does not have the long held notes to create standing waves like a tone generator.Thank you for your great questions!

YES! Firefly. I never turn my back to the camera but the back says "I aim to misbehave"

Hello RemcoK4,Thanks for commenting! What in particular surprised you the most?

It was exciting to see. One thing to be aware of before doing the sugar snake my clothes smelled like a roasted marshmallow for a long time.Thanks for commenting!

Hello MuzicMaker!I have not seen Altered States but it is on my movies to watch list. My plan is for hijinks but without the hallucinogenics. There have been various things that I have read about the potential impacts of ironically extended exposure to sensory deprivation. I would imagine it might be a little bit like holding your breath. When you first try you might not be able to do it for very long but with training and practice you get crazy free divers.I am not sure if I will ever ride the tank for 24 hours but I will definitely update the instructable with how an extended period in the tank goes once I have the chance.Thanks for reading the instructable and commenting!

I am planning on looking it up but it would be great if you added to the instructable how a Ruben Valve works. Curiosity bit me here is an interesting link that I found:http://asevet.com/resources/circuits/magill.htm

Hello CasualBuilder!Thanks for the compliment. These times are one of the major motivations for building this project to be able to better care for family and self during stressful times.P.S. I like the Hobbes profile picture.

Hello ThomasW2,I have not seen that movie but I have hear about it.With all of this time on my hands working from home I will have to give it a watch.

Hello AngstromLogic!I had heard that Feynman had used them but I will have to check out that link! Thanks for contributing to the comments and yoru encouragment!

Hello SteveMann!Thank you for the support. I see a board underneath you in your pictures is your tub full of just water or are their Epsom Salt in there to improve buoyancy? That is a great idea to use a VR head set. I will have to look into that as a potential for exploring a theater solution.I will have to give those links a read.

I appreciate your compliments and I am looking forward to seeing more of your work as well!Right now I am spec'ing out lift assist pistons to make sure that it is an easy lift to get in and out to prepare for turning that tank into an immersive theater!

This is such an awesome project!!! Thanks for sharing. I vote for seeing a video of this being played as well.Your original project drawing are beautiful it would be interesting if you added a few steps for how you made them as well!

Hello StewartH1,I will have to look for that. There are a number of really great guides and designs out there so there are multiple ways of approaching this project. Having a smooth and more uniform output path would help a great deal I am sure. Testing the project has shown me that most of the air is coming out of the little corrugated humps so the air is coming out like a shower head in a collection of little streams instead of a consistent ring but that ends up getting spread out as it gets further from the corrugated tube.If you find some links to the design that you are talking about it would be great to have you add them in the comments.Thanks for commenting!

Hello GaryWieder,How much space do you have height-wise? A lot of what options you have depends on what space you have because just like this project while the output does not have any blades in it the leaf blower was needed to make the air move.One thing that I am really looking forward to making a spin off of the air umbrella I did on my youtube channel which is to make a Waddle ceiling fan which is a type of centrifugal fan with the shroud integrated. This might work in your case because it could be made very thing and there would be very little exposed to interest children especially if you put a second shroud around it which could be used to hold your soaker hose and evaporation cooler. I will keep thinking about this and see if I can move this idea up on the project list.Thanks for …

Hello GaryWieder,Well hopefully unless your kids find a ladder it will not pose much of a risk to them. The ability to control the direction of the air coming from the fan will likely really increase its profile or would create a complex distribution system for the air since you would want this to counteract or to work with the wind?I will have to keep thinking but trying a centrifugal fan concept like I said above seems like it would have potential because it would be a 360 degree flow of air and since the air would be cooled down slightly it would then descend from the ceiling.
