High school chemistry
Remember the experiment where you drop some magnesium in hydrochloric acid and watch it fizz?

Remember the teacher saying that the bubbles that were formed were hydrogen?

Remember what happens when hydrogen gets near a spark?

Now imagine the class Beavis getting an idea in his dim little brain and sparking a lighter over the top of a glass test tube.

I'm very glad I wasn't nearby.

Chemistry
I only got as far as GCSE Chemistry, it not being my forte, but I had a fleeting memory of the result of doing this being an excellent little 'wheep!'

EDIT: LOL! See post below this!

It is
if you only put in a little magnesium, and don't try to accumulate it.

In this case the result was a bit more dramatic.

EDIT: yes, I noticed that just after I posted this. Feck.
