Oogoo

Unread postAuthor: Tipsypyro » Thu Feb 06, 2014 3:22 pm

Has anyone here done any experimenting with oogoo (silicone and corn starch)? I made a piston for a 1.25" chamber out of it and it seals beautifully, but it wont release above about 10 lbs. I assume it's because of the silicone expanding on compression so I'll just have to build a solid piston. It makes great bumpers and washers though and I thought that if you hadn't tried it, people here could come up with all kinds of uses.
Also, I just came upon a used BA tank from the fire dept. 2500 lbs. I was thinking of just using it as a chamber supply tank but I wondered if anyone had any suggestions for a more direct use.

Interesting, never heard of it. Does it degrade with time/humidity etc?

Can it be cast, some links about the stuff would be most helpful :)

Most likely, this happened to me when I used solid rubber pistons at higher pressure.

High pressure BB machinegun!

This stuff sounds interesting. I can think of a ton of applications for stuff other than spud guns. For spud guns less so. As you said piston bumpers might be one application. Molds for projectiles of parts might be another. Insulating or fully potting electronics either on the gun or in the projectiles might be another. That said I am sure there are others.

I am anxious to tinker with this stuff. Using fibers, powders, or other additives to change it's structural properties might extent its usefulness.

"That really isn't a potato cannon anymore, is it?"

I prefer to mix 1:1 without a thinner and there is about a 2 minute window where is is clay-like and can be pressed into a mold. It can also be used to make a mold for epoxy casting. Have fun!

Fascinating! Wonder how it compares to less improvised mixtures as supplied by folks like smooth-on
