Interesting factoid ... the classic stench of rotten eggs produced by a stink bomb is produced when the ammonium sulphide in the stink bomb breaks down to hydrogen sulphide and ammonia.
Ammonium sulphide is an unstable compound and decomposes into ammonia and hydrogen sulphide... An equilibrium is established between the hydrogen sulphide in the headspace of the container and is dissolved in the solution. As soon as the container is broken, the dissolved ammonium sulphide rapidly decomposes and liberates copious amounts of the stinky gas .... really stinky gas, and also dangerous ... Hydrogen sulphide is one of the most toxic gases known and can be lethal in concentration ... thankfully stink bombs dissipated quickly, however that's the reason they were withdrawn from the market.
My Primary School uniform too
Who remembers what this was used for?
To donner unruly kids
Actually, to open and close curtains that were very high up. I remember this from primary school. The curtain rail in the classrooms was high above the windows.
Never pressed the rewind button and always had a pencil in the car...
Actually much later than my childhood!
My Dad's cars when I was a little girl.
I remember the adults playing a horse racing game similar to this. The horses had magnetic feet and were placed on a type of vinyl sheet that I assume had a metallic base underneath and you cranked a handle and the vinyl moved in a vibrating movement back and forth and the friction moved the horses forward. I do remember they fell over often and had to be placed upright on the board often.
