I taight my wife the jewelry and silver cleaning trick years ago. Works great but it takes some practice to learn how to do it. Her grandmother gave her the family flatware set and that was the first realy job we did with it after practicing on some cheaper jewlery first. Works like a charm but really just takes off tarnish but does it well.

Erick, I don't know why your source would say to "tightly cap" the bottle when making hydrogen by putting aluminum foil in ammonia. Given enough of the reactants, the bottle would probably burst or blow its cap off from the pressure. Aluminum will react with any strongly alkaline solution to give off hydrogen. It doesn't need to be confined to make it work.
As a kid, I once put aluminum foil in a Coke bottle with Draino (sodium hydroxide) & water, and put a party balloon over the mouth of the bottle to fill it with hydrogen. It floats like a helium balloon when tied off and let go. This is EXTREMELY dangerous if you don't first let the evolving gas chase most of the air out of the bottle before putting the balloon on, because a mixture of hydrogen and air is violently explosive and even a slight static spark from rubbing the balloon could set it off.

fluffy is right. As kids, we used to combine balls of foil + bathroom cleaner in a sealed 2-liter bottle. The chemical reaction would build incredible pressure causing the bottle to swell/explode. Be very careful what you're "tightly capping" as this is rather dangerous advice.

I agree with Fluffy and lancescape. When I have done experiments to make hydrogen usually just using two probes, two test tubes, a battery & water, I have captured the hydrogen in something that can expand and then ignited it (after a very small amount has been produced). I will update the article to note this.
I saw Steven Segal blow up bad guys using foil, a microwave and something else on TV. That's the one I wanna try. :-)
Nice page Erick. Welcome back.
Acid...Dry ice, a little bit of water and a plastic bottle is fun ittle experiment. Just make sure you stand plenty back. :-)
