Alright for this experiment you'll need the following
- String
- Sticky Tape
- A medium size balloon
- Drinking Straw
- Thread the string through the Straw and tie the ends tightly between two points in a room e.g between two drawers, etc
- Inflate (blow) the balloon and keep the neck closed between your fingers.
- Fix the balloon underneath the drinking Straw with the sticky tape and pull the balloon to one end of the string as seen in the picture below.
- Pull your fingers against the mouth of the balloon then let go
The balloon shoots along the thread with great speed.
Because: when the balloon is closed, the air presses equally along the inside surface.
When the balloon is let go the air inside expands.
