Hello! Im in 9nth grade and my school is very very strict to science faris. They want us to like create things that will help the future or like that, and they don't realize it's very very tough. So what im asking for is a viable theme (not reserch, you have to take action in the process) except for cosmetgic and things like that, because they can give allergies.
Examples our professor gave us was to: invent a new soda, or to cover a super new and cool thing like molecular cooking (we can't use that one, already taken)
Please help me! Im in a hurry and please dont say like pollution or volcanos and stuff.
Sorry for the english, not american
Thank you
Dani.
