Enoch's Solar Balloon

Enoch was finally able to get out his solar balloon.  He was so excited.  It was his favorite present and he had to wait to use it.
Such a simple idea, but full of science and fun.  Enoch's favorites!
He held the balloon over the heater vent to fill it up.  He tied it up. Fastened a string around the end.  And took it outside.
It started floating right away!

Such excitement!

And - no holes!  I was sure there would be a hole in the thin plastic because Enoch got it out so much to look at it.

He has had it out a few times since.  And every time is just as fun!
