We found a great experiment at
that shows how cold air
is more dense than hot air.
Its the same idea as a
hot air balloon.
The hot air in the balloon
is lifted by cold air rushing in
For the experiment, you'll need a tea bag.
Carefully remove the staple and trim off the holes,
making sure you still have a flat edge.
Set the tea bag up like a cylinder.
We put ours on a fire proof surface.
Light the top and watch closely.
The last remaining bit of the tea bag will shoot up
into the air and finish burning.
The kiddos loved it!
