hi everybody, can you give me some ideas on what to do on our science investigatory project this upcoming schoolyear? making ropes and papers doesn't stand out anymore. i think it never did! so as the improvized water distillers and the insect repellants! i really need your help! i'm in highschool by the way. every bit helps! thanks!

There are so many threads like this, it's coming out of my ears.

you could build a electrochemical cell to power a photon emmiter.

This would be the perfect kind of thing for the wiki imo...
