Re: Don't try this at home...
In my last year at Junior school (1963) we had the final term for a"science" lesson once a week.
We were asked to bring in suitable items.
My dad, a refrigeration gave me a steel cylinder with nozzle and valve containing about 4lb of liquid freon 12 to take along. He attached a label with the chemical formula and boiling point etc.
I had great fun running around the playground squirting at the backsides of other lads in my class!
I thinknthere must be a small hole in the ozone layer that I was responsible for.
In latter years I have occasionally used freezer spray as an anaesthetic when removing steel splinters from my fingers.
