Chemical waves – bz reaction

Finally got around to experimenting with the reaction – trying to work out the best way to get a dramatic visual result – sandwiching the mix between glass and the base of a petri dish worked well – but the waste gas product creates bubbles which eventually obscure the reaction – so we tried to get an even covering over the glass by getting it perfectly flat.

Nicks brother had an idea to try the reaction vertically – which worked amazingly well.
