I certainly think Hydrogen would be more fun.
I did actually have a dream, about a chemistry teacher making oxygen and hydrogen bubbles, and allowing them to combine and float up the the ceiling to cover a part of the ceiling tiles. Then applying a lit taper - completely destroying the ceiling!
- Great lesson that everyone remembered.
My School chemistry teacher was just as mad. He entered the classroom late one day when everyone was waiting for him at the tables, with a bottle of sulphur dioxide under his arm - then opened the valve.
Rest of the lesson was outside.
I think I have tasted most things I shouldn't have -engine oil, gear oil, brake fluid, petrol, diesel, paraffin, detergent, meths, machine coolant, ethylene glycol, washer liquid, ink, sulphuric acid, trichloroethane, cyanide,
