Rocket Using air pump

Materials
1. Bottle
2. Cork cap which fits the bottle tightly
3. Cello tape
4. Air pump
5. Scissors

How Do I Do It
1. Take the bottle and connect the air pump using tape, after cutting the base to the correct size of the pump's nozzle.
2. Half fill the bottle with water and shut the bottle using the cork.
3. Keep filling air and the cork would eventually blast out from the bottle

Enjoy
