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

Sounds like combustion to me. What /who is 4chan? L

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.


You actually went to /b/?! I can only imagine...

(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".

... ok wow. 4chan is better at coming up with ideas, than you guys are. which is sad because its 4chan. come on! (actually, 4chan's given me the best advice all night. go 4chan! =D)

  • 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.
