YOU NEED:

• A sugar cube
• A steel container
• A Match Box

Chemical reactions often require a catalyst to aid the reaction. To illustrate this, place a sugar cube on a plate. Try to set the cube on fire with a match stick. You will find that the cube will not burn. Then rub a little cigarette ash on the cube and it will immediately catch fire.

HOW  DOES  IT  WORK?

This happens because the ash works like a catalysts and helps in burning the cube. Remember a catalyst is an agent which helps in a reaction without changing its own state.
