Step-by-step tutorial
Step 1
Gather your materials!
Step 2
Prepare your tea bag. Remove the string, staple and tea from the bag.
Step 3
Unfold the bag so that it is a cylinder. We trimmed off the ends so that it would stand flat. Place your tea bag cylinder onto a non-flammable plate
Tip
For Halloween fun, draw a ghost face onto the tea bag before you place it onto the plate!
Step 4
Make your predictions! What do you think will happen once you light the tea bag? Once you are ready, have an adult help you light the top of the teabag cylinder.
Final result!
What happened? Did your tea bag lift into the air? When the tea bag was lit, the flames started to heat the air within the teabag. The heated air rose above the cooler dense air (similar to a hot air balloon!). Once the teabag was burned, we were left with the lightweight ashes of the tea bag. The lightness of the ashes combined with the heated air caused the tea bag cylinder to lift into the air.
