Chemistry lessons
At high school we were at the stage where they were teaching us really useful stuff - sex education and the reactivity of metals.
Due to health and safety (or more likely because the teacher knew us too well, even though we were top set) we weren't allowed to chuck caesium and rubidium into buckets of water and had to settle with sodium, magnesium and potassium.

The magnesium came in a nice roll which someone half inched and it came to break time which allowed groups of people to go off down to the bottom of the grass bank out of sight of the teachers for their morning's nicotine fix.

We convinced the person who had brought the tobacco and papers that day that smoking a fag which had a couple of strips of said magnesium rolled into it would give it much more of a kick (we convinced him using our knowledge of SCIENCE).

We pretended to play football while they went off for their smoke but got bored because nothing happened. Then all of a sudden expletives were heard and we turned to see a huge cloud of white smoke rising up from below the school yard followed by some sheepish looking smokers coming back up the embankment (I'm sure one of them had less eyebrow than before).

That was our laugh for the day. We gave them the rest of the roll of magnesium but don't know what they did with it.

Length? 100mm in the fag and about 2m left on the roll.
