Tuesday’s Toolbox

Tuesday's Toolbox button

My dear 9-year-old has a fascination for all things WWII. Submarines, naval battles, aircraft carriers…atomic bombs. How about building a Plastic Hydrogen Bomb? Now, don’t go all ballistic and sic the CIA on me! We’re not talking about a radioactive device of mass destruction, but a simple Science Toy You Can Make With Your Kids at home:

It sounds like the perfect terrorist weapon, but it is a toy that teaches the principles of electrochemistry. It's also a high-tech squirt gun.

The Plastic Hydrogen Bomb uses electricity to break apart water molecules into hydrogen and oxygen. Then it uses a spark of electricity to explosively recombine the gases into high pressure steam, which propels a stream of water high into the air.

There are several other awesome projects on this site, including a film can cannon, a homemade vacuum pump, a rocket engine…What I love is how everything is explained step-by-step with plenty of pictures and diagrams (I’m very visual), and there’s a full explanation of the principles behind the toy. A little advanced for my crew, but something to bookmark for later on.

  1. Explosions are always so much fun!

    I hope it's OK to double up a review post for this meme; we found out that Family Mint is super-tweakable and have been having a lot of fun with it. LOL

  2. Wow! We went to look at that website after seeing a picture of a rocket in our science book, but it's way too complex for my hands-on little girls.

    The older kids aren't hands on anymore. But an older kid could have so much fun learning from that website! I've bookmarked it.

  3. My hubby is has been waiting for the kiddos to be old enough---he has his sites set on the gauss rifle. Even if they could to the actual project, they're just not old enough to understand the concepts behind how it works.
