bouncing bubbles

Here is a how-to on making bubbles that don't break so easily:

The trick is to add glycerin to Dawn dish soap (for some reason it is the best for bubbles) and let it sit overnight.  That allows the glycerin to crosslink with the soap and create a stronger bond when blown.

You need to have some cotton or soft knit gloves to hold the bubbles and bounce them.

There is another option using dry ice to make fog filled bubbles too:
