trying to come up with a good and interesting science experiment topic/idea.

at high school level. this need to be do-able, ie. no requirement for high level knowledge or advaanced technology.


the science experiment idea need to be appealing.


I'll pay up to 400fgs just for a good idea.

Creating pure hydrogen gas using aluminum foil and hydrochloric acid. Then blow up the hydrogen.

put some aluminum foil in a bottle of hydrochloric acid, close the cap, find some cover

you could buy one of those hydrogen powered remote controlled cars and demonstrate how water could be converted to be used to power vehicles
or
this is a really fun one tells you what u need to do it too

what sort of science? be less vague...

if you want an experiment without studying the primary sciences as primary sciences alone, you're asking for something entirely different.

anything related to physics/chem/or a bit of both would work.
the topic is broad as hell. need to be interesting and innovative.

chemistry i can do. how far into chemistry have you gotten? inorganic or organic?

physical chemistry is the easiest to perform experimentally as far as presenting it goes.

make a cubic bubble. bricks will be shat.

Before you close the cap, fill a balloon with the pure hydrogen that comes out.

dont think cubic bubble will cut it
