Chemistry
I dont think you ever appreciate the crazy things you see as a child until
you get a lot older.

Many years ago in the 80's i had a chemistry teacher who was a complete mentalist. Whilst he was talking to the class he would wander around the students tables surveying his domain.
If anyone dared to talk he would wander behind them and continue to discuss what he was talking about at ear drum piercing volume behind the "talking" persons head whilst spraying them in spit.
My favourite distraction was when a friend of mine left his Head Bag (a fashionable bag at that time) on the table.
My chemistry teacher hated bags on tables and everyone knew this fact because he would tell everyone this fact with regularity.
anyhoo ...at the start of the chemistry lesson in question my classmate not only left his bag on the table but also proceeded to talk after everyone else had settled down.
My teacher calm as you like strolled over to the bunsen burner next to my friend turned on the tap and lit the gas.
This resulted in a five foot flame that not only people in the vicinity could feel but that also burnt the fashionable bag in question.
The teacher then turned off the tap and calmly took a chemistry flask and extinguished the bag which had ignited using some water from the sink.
The class then proceeded to continue as normal.

it wouldn't happen now but then he probably isn't teaching anymore.
Most people might think "what a prick" but a valuable lesson was learnt that day in class
and that was sometimes people should know when to shut the fuck up.

That sounds like....
bullshit to me! I've worked in the supply and installation of gas taps for many years and the flame could never go more than a foot!
