Hello,Sorry about the late response, I haven't checked on my account in a while.I didn't actually need to use any other cleaning agents surprisingly. One main reason for contamination may be from the air. Since my bottles are capped and sealed, there is a less likely chance that contaminants will get into the bottle. It also helps to use clean filtered water or the water that came in the bottle itself. I would also suggest keeping your bottles in an indoor climate controlled environment if you currently have it in a garage or outdoors. I used a laundry machine tub as a base just in case the bottle leaked and would have spilled water on my carpet.I would also check on the starter culture that you are adding.

Generally speaking, test tubes of algae from online or labs should be fine but if you are sourcing starter cultures from nature such as a pond or river then you may get unwanted contaminants. Lastly, Chlorine bleach sounds like a hassle to use - I would suggest trying out some isopropyl rubbing alcohol. A high percentage such as 95% should work well to clean anything off the inside surface of the bottle. Just swirl around a few tablespoons (or wipe it down if you can) for a few minutes and drain the excess, then repeat one or two more times.
Fruit Caviar - Molecular Gastronomy
I have not read that survey, will do. Corn is not as good at producing lipids (and even starches) compared to soybeans or algae though.
Hmm, Interesting. I will do more research on that. Thanks for the suggestion!
Interesting point. I may have to add in a buffer solution to prevent pH changes. This could work well in low pressure containers since solubility of gases increases with pressure, but solubility of solids tend to decrease.
Good point. Being able to capture from existing sources of CO2 was one idea I had (which I was talking about below as well). The one problem I would have to bypass would be toxic chemicals in the smoke such as arsenic. With smoke scrubbers and some filters, that is definitely a feasible idea. What I meant though in my earlier comment, is that if I need to produce CO2, such as making cartridges, then it wouldn't be environmentally friendly.
I didn't research the exact wavelengths, but I put purple light in general since chlorophyll absorbs it well. With the LED strip, the light color can be controlled better as well.
Thanks for viewing!
I have read in some places how to not have the algae under light all the time. I did cycle lights for a while but I just kept them on the whole day later on. I will need to research the rest periods and maybe integrate the LED strip with my arduino circuit to automatically turn them on and off. Thanks for the advice!
A friend of mine actually used a lab centrifuge to get algae before, but yes that would be impractical for mass production. Filter is definitely the way to go. Good point on the aluminum foil. That light is indeed being wasted. For my experiment however, it was important that I can monitor the algae growth rates. For a more of a functional photobioreactor than one for experimentation, foil is the way to go.Thanks for the encouragement! It really shows what Instructables is all about.
I'll keep updates here!

Wow this looks really cool!
Wow I have the same exact design cannon except I used the same size pipe for the barrel as the pressure chamber to shoot water balloons. I found that if you use a 3/4 inch barrel (or the same size as the valve output), it can shoot paintballs and paper rockets quite far!
Wow this is so creative!

I always wanted to try and make one of these, but I couldn't figure out how to make the LEDs sync up properly with the speed of the spinner

I was never into fidget spinners, but I have to admit that this is really cool. Unique idea!
Wow cool idea!
I have added a small video that can be viewed. I don't have a YouTube channel so I couldn't embed it, but you can download and watch it if you are interested. :D
The humidifier is the ultrasonic module and is simply placed in the lower tub. I'll add the step in. Thanks for the feedback!
This is cool video of a fire tornado with no moving parts: It works because the flame wants o go upwards. In my design, I use fog so I need a fan to pull it up. And since I wanted to make it open air, I had to use the straws in configuration.

That is an interesting pointer. I never actually considered how the air would warm and cool and affect the pressure inside the bottle. The outside temperature could also have a play in it. In the design, after a bit of wear (like a month or so) the cap does leak a teensy bit and I simply changed the cap, but adding a O ring would probably help too. My only other thought on your idea is, since the bottle is thin walled plastic as well, wouldn't it just expand and contract as needed? Or even if it doesn't, would the plastic balls change shape before water begins to leak out.A simple solution would be to add air vents in the bottle, but because of the water inside it's probably not a good idea.Thanks for the feedback, I appreciate it! :D
and is there any way to make the battery last longer? Would a battery salvaged from a prius for example give longer runs. I know to get a car to run as long as a tesla would be very expensive but maybe around 100 miles per charge would work with a few solar panels on top to make that even more?
If I wanted to build a sports car, would I need to make my own custom motors or buy different ones? Also, in most electric cars, does the motor transfer motion through a transmission... I thought they were connected directly to the wheel and the voltage was controlled to change speed.
