The Experiment of Fire and Hot Air Balloons

We found a great experiment at

All Things Beautiful

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

underneath it.

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!

Wishing you homeschool blessings,
