Chemist advice needed....
 

Any chemists out there?

I need to create a reaction similar to the one you get when you mix vinegar with baking soda. However I need to create it using only dry powders.

It needs to be non-toxic in small quantities, stable over long durations (ie no dry ice), and not to expensive or hard to acquire.

Anyone have any ideas?

Define "similar". Is it release of CO2 that you're after?

CO2 is not important, I want the POP.

With foaming and bubbling and such?

I just want to mix A and B, seal it in a baggie or soda bottle and have it go pop like you can with vinegar and baking soda. I just don't want the liquid.

Um....whatcha doing Moonie?

Uhhhh..... nothing... :blush:

Just a little kid project, yeah that's it. Kids project. That's my story and I'm sticking to it. ;)

I think you're just tryin to scare the hell out of Santa as he slides down your chimney.

Can't do it without liquid. Sorry.

You could try mixing baking soda and citric acid powder in a baggie and then enclosing with it a little fragile container (mini-ziploc, wax-encased, small water balloon or similar) of water, then rupture the small bag, and watch it pop.

I can think of several essentially dry combinations that will provide pop but not in ways that wouldn't draw the attention of the ATF. At least not a chemical "pop" (read: explosion)

If you want to get pop by creating gas that overinflates a container that probably means a CO2 producing reaction since most of the other easily produced gasses are toxic (I'm assuming you don't want to end up with an ammonia cloud), and all I can think of still involve a liquid. I'd also think that if only dry components were involved the reaction would likely be too slow to produce a dramatic effect.
