(Instant ice when it gains heat)

From my understandings, it may gain too much heat until it was crystallized. As it was inside the plastic container and then you can see the heat flow from throughout the liquid. Amazing huh?

Do not try this at home. haha

Dish soap is placed in large flask with 20 mL of 30% hydrogen peroxide. Two different colours of food colouring are dribbled down the neck of the flask. Add 5 g KI powder and step back. The exothermic reaction produces heat and oxygen gas and a lot of foam. Plunge a glowing splint into the foam. The pure oxygen will cause it to relight until it gets too wet.
This activity is excellent for discussions about catalysts, exothermic reactions and decomposition reactions.
2H2O2 = 2H20 + O2.

Thanks for viewing,
more coming up soon! ^^
