Go Green, Little Scientists (2)

Besides the solar toys, we also made a few toys powered by rubber band and air.

My flipping butterfly.

The power of boomerangs


Letting the birds flap and fly in the air!


Birds that can flap their wings and fly - powered by rubber band.


Get set, ready, aim and shoot!  One of their favourite.


Compressed air in the air canon - shoot the enemy down!

Toy car that runs on air!


Blowing air into the balloon to power the toy car.
