Little tidbits of science like this keep my mind from going rusty =)

And would you say mixing the 2 gases in a 2/1 ratio would yield exciting results?

Amazing video. I’ve been trying different set ups to achieve a electrolysis chamber for a while but I seem to never get it right.
Maybe this will work 👍
If you could help what ratio for baking soda to water did you use?

i have a basic setup, a Tupperware box but i have not test tubes, im thinking if using a sandwich bag to collect the clorine and hydrogen since i don't have a chemistry set. Im using zinc and copper and hot gluing them to the bottom of the box with a nine volt battery as shown. im just wondering if this procedure of mine will work or not and if you have any thing you might like to add.

I'm abit confused... Do you just stick the electrical wires upside down? Is it not connected to anything? Just floating around? Or is it connected to something??
