One of the things I find interesting and have found interesting since school, is hydrogen.
This simple atom can be real fun to do stuff with.
One thing that is always interesting is make something that goes boom.
In my case, I replicated a water splitting unit, just for the fun and the bang.
I had an old computer powersupply laying in my junk box, and this fits the job perfect,
as I needed around 12V with enough current to make suffecient hydrogen and oxygen.
A picture of the setup:
Goggles in the lower left corner, those will be weared as soon as I turn on the powersupply, just to make sure nothing happens to my eyes.
And of course also when I light the bubbles.
The setup is a single computer powersupply, where the 12V output was connected directly across the stainless steel bicycle spokes.
A 5 mm rubber tubing hotglued to the top of the bottle lid, running down to a container with soap water.
In the cell itself, just plain tap water, but added a bit of NaOH (Toilet cleaner, or whatever you call it), 30 mL or so.
WHEN YOU HANDLE CHEMICALS, MAKE SURE TO WEAR GLOVES AND GOGGLES!! Also, a good ventilated area is a nice thing to work in with these thing.
A short video demonstrating the “purpose” of the setup:
Always remember safety when you do things like this.
I’m not responsable for any damage to you or you equipment.
