# Would consuming the Belousov-Zhabotinsky reaction be dangerous? [closed]

I'm wondering if the chemicals involved in the Belousov-Zhabotinsky reaction would be at all poisonous. If at all, do you know of another similar oscillating reaction that could safely be ingested?

 Seriously, I was wondering if it would be possible to invent a candy that changes flavors in waves. I know Turing came up with a mathematical demonstration of the possibility of this sort of reaction long before its discovery which makes me think that others exist.

Here is the apparent chemical reaction:

$$\ce{3CH2(CO2H)2 + 4BrO3- -> 4Br- + 9CO2 + 6H2O}$$

• An oscillating reaction would be a terrible way to make a flavour changing candy and exceedingly complicated. You can't easily control the environment and the environment of the reaction matters to the speed of the cycles. Why not just make a candy with different layers with different flavours: solubility will do the job of changing flavours. Jun 10, 2016 at 8:56

3. At least three distinct steps that are all forward reactions where it goes $\ce{A->B->C->A}$ (you don't want equilibrium reactions because these tend to find a middle ground much faster)
