Depends what reaction you're using.

Changing temperature or ratio can often work.
I think this is what SluffAndRuff may have been getting at, but you might consider looking at other reactions, there are a fair number of fast gas-producing reactions out there.

EDIT: If you were trying to decompose H2O2 for the photochemical task earlier, I'm not totally sure what the best course there would've been. More light?

I'm still uncertain as to how you would hold the reactants up using a magnet. Would the solid reactant be in a little basket like thing?

Does anyone know the definition of a balloon? Must it be a manufactured balloon or can it be homemade from Mylar or a grocery sack? Generating gas pressure to inflate something is much easier than actually inflating a balloon.

I'm just wondering, what is your take on ballon. because I think that a plastic bag should work

That's getting really close to not a balloon... why not use a long balloon? You can get ones that are really narrow. Mine are 1 inch diameter.

Re: Balloon Task

This is a post made in desperation after our original idea failed.

For the balloon task, we wanted to use the decomposition of H2O2, using MnO2 as a catalyst. It failed with the 3 percent H2O2 that we used. (Failed as in only the base of the balloon swoll, maybe 1 cm, and didn't increase from there) What's worse is that we were using this for our chemical timer as well.

Advice? We have a competition in two weeks, so we're stressing out right now, so any help is much appreciated.

EDIT: The only problem that we have is that this was meant to be our chemical timer, otherwise, we could just use the baking soda and vinegar.

Ideas to protect the seal?

Post by Ash123 »

Hey Guys
Does anyone have any ideas on how to get the balloon onto the vessel that contains the chemical reaction? I'm stumped on finding a way to force the balloon onto, say, a beaker filled with baking soda and vinegar.

if you were to use baking soda and vinegar but still have the chemical timer you can put the baking soda into little pill capsules that dissolve in water. this will delay the reaction
I hope this helps
