On the first experiment, they use a pepper-like substance called Potassium Permanganate (KMn04) which is an oxidant and an oil-like substance called Brake Fluid which is a fuel. When they combined these two substances in a stainless container, this results on having a little fire on the container. And they said it is because of the Chemical Reaction made by the two substances and the mixture should release energy in the form of heat that’s why this results on combustion. At first, I thought that the Brake Fluid they used is just a simple Cooking Oil and the Potassium Permanganate is just a pepper.But those “simple� substances I thought made an amazing experiment which makes me understand how heat was released by a Chemical Reaction. On the second experiment, the special substance they use is Dry Ice – which is a Frozen Carbon Dioxide – together with a balloon, funnel, mortar and pestle (to crush the Dry Ice) and a bottle with water.
