Science Experiments with Balloons

My children love to play with balloons. Do you have some activities that they could do with balloons that are fun and educational? - Love Balloons
Answer: Your children can have fun and discover some scientific principles using balloons in the below activities. They will need your help with these experiments to do them easily and safely.
Experiment No. 1: Does air expand when it is heated? Blow up a balloon and measure the distance around it at its widest point (circumference). Next, turn on a lamp and hold the balloon above it for 2 to 3 minutes. Then measure the distance around the balloon's circumference again. What happened to the size of the balloon?
Experiment No. 2: Ask your children if they think that it is possible to stick a pin in a balloon without popping it. Blow up a latex balloon until it is about three-quarters full of air and tie off the end. Next, cut seven pieces of strong, sticky tape and secure each one firmly to the outside of the balloon. Try to space them evenly. Then carefully stick a straight pin through the middle of each piece of tape. Why didn't the balloon burst? (The sticky tape forms a seal around the pin.)
Experiment No. 3: Play the water-toss balloon game. Have teams of two players toss balloons filled with water back and forth. Go back one step after each successful catch. How can you win? Move your hands backward as you catch so you are not abruptly stopping a balloon's momentum.
