Create a Bubble Table

Wet a table top, get some drinking straws and a little tub of bubble mix or detergent. Dip an end of the the straw in the bubble mix then put that end on the wet table and blow gently to create half bubbles.
See how big you can get the bubbles, how many smaller bubbles you can get inside one bubble or how many layers of bubbles you can create inside each other. Try sucking out the air after you've created a bubble and see what happens.
Is the word bubble mentioned in the Bible?
