In this article you will learn how to easily and safely create a rocket ship out of a 2 liter bottle. Great for science teacher and parents alike.

Difficulty: Easy

Instructions

2 liter bottle, a little less than half full.
A bicycle pump.
Common wine cork
optional, construction paper and any other materials used to customize and design "rocket"

Step 1

You will need to first make the 2-liter bottle stand on its own, upside-down. you can do this by using glue and cardboard to apply "legs" to the bottle. a tri-pod formation works best.
Step 2

You will then fill the bottle a little less than halfway with water. Apply the cork to seal out the water from escaping the bottle. Water temperature will not play much of a factor in this experiment.
Step 3

Outside in an open area, insert the needle from the bicycle pump into the cork at the base of the bottle and start pumping slowly. After about 5-7 pumps the air prussure will build and the cork will pop out. This will cause a "blast off" and if all goes well your "rocket" should launch about 30-60 feet in the air.
