Flying teabag experiment

This is a flying tea bag!!! Try this at home (With an adult).

Why does the teabag fly?
Lighting the top of the teabag cylinder heats the air inside the cylinder. The air molecules start to move more quickly and spread out to take up more space. As the air molecules spread out, the air inside the cylinder becomes less dense. Warm, less dense air rises above cool, dense air. The ash of the teabag is light and doesn't require much force to lift it. As the warm, less dense air rises, it has enough force to lift the ash of the teabag.

Here is the link to the experiment http://www.planet-science.com/categories/experiments/surprise/2011/03/make-a-teabag-fly.aspx

    How did you do that with the tea bag.
    Bye. I hope you leave another comment so I can see.

    1. Hi Rosalind
      To make the teabag fly we need tin foil and the teabag but we don't need the tea.
      Then you need a lighter and then you light it up then it will fly.
