chemistry explosion experiments

The pressure inside the bag or canister causes the container to break, creating an explosion that releases the pressure. but no matter what you call it, an explosion is a great way to have fun with science. But the elephant's toothpaste experiment speeds the process with a catalyst, a chemical compound that increases the rate of a given reaction. .". Chemical reaction or change: a change that leads to the transformation of one substance into a different substance.
