Tools and Materials for Arduino
Welcome to Arduino
Hmmm... We don't have palm leaves where I live. Voted!
We used a plastic cup to trap it. It's not very efficient, and we can't seem to ignite it. Probably something wrong with the electrolyte. We tried salt, but it started to smell toxic, so we abandoned ship while holding our breaths.
If you find one of those chargers that looks like two wires fused together, then you can connect those to your leads and do it like normal. Just make sure it's a dc charger.
Made this with a yogurt container and a cellphone charger.
Putting salt in the water can produce chlorine gas when electrified. I don't think it is enough to be dangerous(pool chemicals probably contain more) but better safe than sorry.
Splitting Water the Easy Way
I made mine with a 12 qt steel bucket, and molded the center with a 5 quart paint bucket. Essentially the same, but you can use a 10 lb fire extinguisher for the crucible instead, which gives you a whole lot more firepower. P.S, with a 10 lb extinguisher, it takes hours to make the crucible. I tried using a ball peen hammer to bend a pour spout onto the crucible. It's a nice touch.
