Earlier this week I posted a science problem for you and your kids to work at. Did you? Here are the answers.
#1 - Bend the straw about 3 inches from one end. Insert the short end into the bottle. Pull the long end slowly until the bent end touches both sides of the bottle, then lift. Tah Dah! You lifted the bottle without actually touching it with your hands.
#2 - Insert the round end of the balloon into the bottle, being careful not to let go of the opening of the balloon. Blow air into the balloon until it fills enough so that it touches both sides of the bottle. Then lift. Easy!
I hope you had fun with this and that your kids did too. We certainly did.
