In chemistry...
We were doing an experiment which involved indentifying hydrogen from a "squeaky pop" from combustion.

I can't remember what the original compound we were supposed to get said hydrogen from, but we needed bunsen burners to do it.

So, I choose to work with one of my best friends in this experiment. Whilst I set up the bunsen burner and the other equipment, he went off to get a splint to light to get the flame from another bunsen to ours.

He walks back with a lit splint to our work-area, he holds the lit splint over the bunsen and I turn on the gas tap.

Nothing happened.

I turned the tap off, and then back on again.

Nothing happened.

My mates looks down, and says "you've turned the wrong tap on!" There is nothing particularly funny in this. The funny part is that he then reaches down to turn it off with the hand he had the splint in, resulting in a ball of fire erupting from the gas tap, hitting his hand and travelling half-way up his arm before I turned the tap off.

The general consensus was "shit..."

If you can think of a knob joke suitable here, well you're cleverer than me...

Length?
As long as his forearm but it dissipated quickly.

Sorry.

Well done that man.

Have a point.

No, have two!
