This is a real fun activity. You can find out how to make it here. There is also a good video demonstration of the bouncing bubble too. We mixed the ingredients together yesterday since it needs to sit for 24 hours before you use it.
Each of my older boys wanted a turn blowing the bubbles for the others to catch.
Here is a little video of my boys trying to keep their bubbles bouncing. I could make it last longer, but couldn't video tape myself at the same time. They had great fun bouncing the bubbles.
