how do I build a chemical car? Answered

Hello, my name is Taylor Love. Right now my school is having us do a science project where we need to use chemicals to propel a toy car across the room. sounds easy right? oh wait there's a catch. no combustion reactions, or explosions. :( got any ideas besides the usual baking soda and vinegar trick? any help would be great. if anyone knows how we could make a battery powered car go across the room, that'd be pretty cool too. but we have to make the battery from scratch.

Try a HHO fuel cell. They are under a hundred dollars and can propel a model car a few hundred yards on one charge.

Seems to me that I remember making a battery cell using epson salts, some paper towels, and some thin pieces of lead.....but I can't find a source for how it was done.

I just looked up a few chemical reactions. acetone + hydrogen peroxide

Saying that 4chan is better than you is the blackest, most vile insult on interblogger could give another.

I looked at it once, and something called "b/". I had to go and wash my eyes afterwards.

(Actually, it's not as extreme as they make out - a lot of it was scans from comics and silly comments.)

4chan are the people who just organised an attack on youtube, posting porn tagged as teen-star videos.

The site describes itself as "home of the sickest, strangest, and most horrifying stuff on the internet".

  • Try building a lead-acid battery, using it to electrolyse water, and then using the pressure of the H2 and O2 produced to propel the car.
  • For efficiency's sake, try using the "usual" baking soda & vinegar trick to pressurise an "air hog" type car.
  • A small foam-type fire-extinguisher could generate enough of a jet to power the car.
