3A95.59 - Belousov - Zhabotinsky Reactions
See also 3A95.59 in Chaos and Rube Goldberg.
The mixing of chemicals needs to take place before hand. This also take quite a bit of time, so make sure to allow at least 24 hours to get this demo ready. Refer to the file for chemical proportions and mixing instructions.
For every 100 ml of solution use:
|.55 g||Ceric Ammonium Nitrate|
*For the KBr make a stock solution using .2 grams KBr per Liter. Use 1 ml of this solution for each 100 ml of reaction solution.
