Flying tea bag rocket – Experiment
This experiment should only be done under supervision of an adult!
Material:
A pair of scissors
Tea bag
Lighter
Fire resistant surface
How:
Take out the teabag and remove the string. Cut the both ends open and remove the tea inside. Form both ends like tubes and place it vertical at the fire resistant surface. Light the tea bag and wait for it to fly.
Explanation:
The heated air inside the tube causes the ash that is very light to rise up in the air since hot air is lighter than cold air. Well that’s the short explanation anyway. Discuss it more in the comments.

Imploding soda cans – Experiment
This experiment should only be done by adults!
Material:
Bowl with cold water
Cooking tongs
Aluminium soda can
Hot plate
How:
Prepare the cold water. Add a little bit of water in the can. Put it on the hot plate. When it’s boiling, use the cooking tongs to flip over the can with the opening into the cold water. Now the can will implode and left is the crushed soda can. Remember to be careful.
Explanation:
When boiling water in the aluminum can the air inside will be replaced with vapor. When the vapor gets in contact with cold water it will quickly transform into water, and this creates a vacuum that causes the can to crush.
