I have a quick question that I hope some of you all may be able to help with – every year I do the gummy bear molten potassium chlorate demo to illustrate Cellular Respiration. However after speaking with another science teacher in the area he told me I probably shouldn’t do this demo due to the high risk of impurities in the potassium chlorate – which could lead to disastrous results. Do any of you have any experience with this, or maybe elaborate more on the risks? Thanks
