These little balls are so cool! The boys (and I) had a blast bouncing them here in the house.
I found this idea on http://www.theidearoom.net/crafts.
My guess is that you can use any size balloon
but we used the 9 inch balloons and for a larger ball,
the size above that. Not sure of the exact size.
You take the first balloon and put just enough water in it to fill it out barely.
Then cut the "lips" (ha ha) off of the balloon.
|Stretch the cut balloon out and over the water balloon.|
until you have a thick
covering. I used 7 or 8 balloons on this ball, but they were pretty thick.
Note: I always put the open end into the other balloon.
Voila! Bounce away!
