Chemist advice needed....

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.

Just like a glowstick! Can you find a small fragile glass vial?
