But in all seriousness, this one's tough. There aren't many materials that a) react to light, b) react quickly and measurably, c) don't react in ambient light but don't require a death laser to initiate, and d) are safe.

I already have my material and it was pretty inexpensive... It reacts quickly to light and doesn't react in ambient light. The major challange here is having the idea for the material and how to measure the reaction.

hydrogen peroxide? I really appreciate the hints, I was looking in the wrong places

Does anyone know how fast and how much light is need to start a reaction with hydrogen peroxide? I can't think of any other chemicals that would work...

That might work but I wasn't hinting at hydrogen peroxide... oops

If H2O2 decomposes fast enough, we can connect this to balloon task - another way to expand balloon without compromising the seal

I haven't tested it yet, however.

perhaps this reaction could work?

Edit: nvm, I think chlorine and hydrochloric acid falls under hazardous materials and gasses

I think the chlroine gas would be a
safety issue, and would probably not be allowed under 2d.

Yeah... I probably should have realised that lol.

Bleach and ammonia is a much better reaction
