What substance should I use for this?

I need to figure out what to use for a certain application.  It needs to have small particles, say the size of large glitter flakes, sand, styrofoam balls, or those tiny glass beads without holes that people glue onto ornaments. I'd prefer if it could pile up a bit like damp sand... not too high, 1/2 inch max is all I need.  I need it to not rot or deteriorate in a closed container for an extended period of time, and I need it to not attract a charge over time and cling to the sides of the container (like glitter and styrofoam balls do). I need to be able to push it around easily if, for example, I dragged my finger through a pan of it. I need it to be white or clear.

preventing buildup of glutinous substance on duct walls?

During a manufacturing process, hot air flows through a duct carrying fine particles of a glutinous substance. With time, those particles stick to the walls of the duct and create a thick layer on them. This layer reduces the cross-section area of the duct, changing the velocity of the flow. To remove this layer, the flow has to be stopped. Any ideas of how to remove the layer without having to stop the flow? Or to prevent the buildup of the layer?

food for teeth ?

Hello. I've heard that teeth were able to absorb some substances/molecules thanks to the porosity of the enamel. Unlike bones, as they are not self-regenerating from the outside, I was wondering what substances may be usefull to offset the erosion of the enamel (remineralization ?). Is there something that could be concidered as a "food" for teeth ? Also, about dental caries, as they are mainly caused by bacteria eating "fermentable carbohydrates" who generate acidity, here is a question that may sound stupid, but that is serious : - to make the work of those bacteria harder, is it better to sleep with the mouth wide opened (oxygened mouth) or with the mouth closed (anaerobic conditions) ?

Can you freeze dry food at home?

I would like to know how to freeze dry food. Could some create an Instructable How-To,... Can someone build a machine that freeze dry food? There are essentially three categories of freeze-dryers: the manifold freeze-dryer, the rotary freeze-dryer and the tray style freeze-dryer. Two components are common to all types of freeze-dryers: a vacuum pump to reduce the ambient gas pressure in a vessel containing the substance to be dried and a condenser to remove the moisture by condensation on a surface cooled to -40 to -80 C (-40 to -112 F). The manifold, rotary and tray type freeze-dryers differ in the method by which the dried substance is interfaced with a condenser. In manifold freeze-dryers a short usually circular tube is used to connect multiple containers with the dried product to a condenser. The rotary and tray freeze-dryers have a single large reservoir for the dried substance. Thank You

How would i harden printer ink to stand up to lots of handling (on a plastic-type substance)?

Hello fellow instructable'r,I have been trying to make my own custom guitar picks and, so far, have been extremely surprised with my results. First, i wondered if it was possible for a guitar pick to even run through my printer (regular load in front, print to front) without jamming it. I found out that i could. Then, i tried printing a NIN (Nine Inch Nails) logo on it and it worked. My only problem is that i can't get the ink to dry and become durable enough to let me touch it and not take ink off/ make fingerprints on it. For now, i have put tape over the side i printed on, but is there any way that you know of that i can make the ink more permanent? I was thinking of maybe using clear coat spray or that clear top coat for nail polish. Just so you guys know, i used a yellow dunlop tortex .73mm pick.Thanks,-Nick

All right, let's clear this up: What the hell is inside of a battery?

Really frustrating: I accidentally closed the tab I had been working on for about 15 minutes, so I'll probably be missing a couple of questions I had been meaning to ask.So anyway: When I peel off the outermost metal covering of a zinc-carbon battery, I'm just taking away a protective steel covering, right? When I get rid of that, am I looking at the actual zinc "case?"What is the sticky, black material that surrounds the graphite rod? Is that manganese dioxide? Is manganese dioxide the same thing manganese oxide?Further outwards from the center of the battery, there is another black substance. Is this ammonium chloride?I haven't actually chopped open a carbon-zinc battery all the way yet. Is there a good technique for removing all of the contents?How can I tell the difference between the two black substances? Is the moist, black paste ammonium chloride? If this is so, then why, when I pull the graphite rod out of the battery, is it sometimes coated with a sticky, black substance? Do the substances mix with each other or are both substances sticky and black? Is one a powder?Is it okay to drill through one end of the battery? If I drill into the negative terminal of the battery, what will fall out?Basically, what are the physical properties of all the materials? How can I tell the difference between them?Now: On to alkaline batteries...Both types (carbon-zinc and alkaline) appear to use manganese dioxide. Is this so? On Wikipedia's article on alkaline batteries, manganese dioxide is described as Zn/MnO2, with the two as a sub-script. Does the slash mark mean that zinc and manganese dioxide are interchangeable?What will I find if I open up an alkaline battery? Is it safe to do so? What is a good, safe way to open one up?Are there any particular "fun" applications for these chemicals? Think explodiness ; )I've heard that manganese dioxide can be used to produce oxygen. How do I do this?There might be some yellow tag-box notes on these, pictures. For the context, visit my Instructable on how to make your own carbon arc light. I'm not trying to advertise, I'm just anticipating someone asking about them.

What natural substance can I use that has a tacky feel to put on my dogs paws that is non toxic to dogs?

My dog had a spinal op,and was recovering nicely. I have polished floorboards that are an absolute nightmare for him to walk around on. The list of remedies I have tried are endless. Dog socks,boots,shoes,mats,balloons etc.I have spent a small fortune with no luck. We have non slip mats around but I can't cover the whole house in rubber mats. I've trimmed his nails short,and the fur between his toes,but I've noticed his paw pads are really dry. I'm trying to formulate something that I can put on his paws that has a tacky feel. I'm no scientist but I've wracked my brain to come up with a solution that is easy to make and not toxic. It has to be something that doesn't taste fantastic because he'll lick it off. As a sample I tried some tacky hair wax..which just gave him a little grip,but it's not what I'm looking for. I know beeswax is sticky,but i think it needs to be mixed with something.I had a feel of surfboard wax,but it didn't have enough tackiness for what I want.I know honey is sticky but don't think I want that all over my floor.Also pine sap is sticky too. I guess i'm looking for something that feels like those silicone non slip dots you can buy that is safe for animals? Any suggestions?

Yo-yo Friction Stickers - are mine "used up"?

I bought a Duncan Mosquito yo-yo 2 days ago, which is the first one I've owned that has a ball-bearing axle and friction stickers. I have been pleased with the long sleep times and pretty good response. Lately, however, both of those have been not so good. The sleep time is okay, although it is somewhat weaker. It seems my string is sliding off of the yo-yo and not getting enough friction to give it extra spin. The previous problem may be related to the following one. When I bought the yo-yo, the friction stickers (which are rubber) were coated in a somewhat sticky substance. After playing with the yo-yo and examining it every now and then, the substance has worn off, and there is no more of it to speak of. My yo-yo has experienced an extreme decrease in response, except at high spin speeds. Although I have learned to bind, I would prefer my yo-yo to respond at least a little bit. Are my friction stickers already ruined? I'm not a pro, so I don't guess I played with it too hard. Is there anything I can do to "fix" my stickers? Thanks, and good luck to all who enter the contest!
