We saw this on tv. The boys wanted to make it and so we did.
First we blew up a water balloon. It was a little hard, but we finally did it.
Then we added a little wool for the tail and a little piece of blue tack to the end of the wool.
Then we stuck 4 pieces of square orange paper to the balloon with sticky tape.
The boys then took turns at blowing the helicopter around and around with a straw.
And, yes, it was very hard to get a photo of this as the boys and the helicopters kept moving.
This is a picture of the balloon helicopter so you can see what it looked like.
