Better find the quantity of each ingredient first--and I wouldn't be surprised if you had to grind up the magnesium yourself. And--TRY IT OUTDOORS FIRST! Allen

I once threw some chemicals together in a test tube and ended up with some sort of mild acid. Some spilled on my shoulder when I shook it and burned through my T-Shirt and burned my skin. It's amazing they were legally allowed to sell those kits for kids and it's obvious why they are no longer on the market to buy.

One day I decided to generate hydrogen sulfide gas. I also had a war surplus gas mask, so I really had no idea of the quantity I generated. Let's just say my neighbors were not pleased with my experiments. In high school I majored in chemistry. We would run down the halls with one guy carrying a gallon of muriatic acid and I would carry a gallon of ammonia. We would each leave a trail of our respective liquids and when the two combined, clouds of ammonium chloride would be generated. The school officials were quite tolerant and we only got a few days of detention. Today, I could see newspaper headlines claiming we tried to blow up the school. -- Peter

Then, he returned to his desk at the front of the class, waited for everyone to become thoroughly engrossed with the test, and set it off. Most kids were so stunned, they didn't even scream; others howled and hit the floor. He and other teachers chuckled about it for weeks afterwards. Today, I'm sure he'd have been fired on the spot, maybe even had charges to deal with... Humour has changed a lot over the years... Take Care, Dudley
