Skewer a balloon?

Students in Mrs. Rainwater’s science class were holding their breathe as they started to puncture their balloons with a wooden skewer - because everyone knows that a balloon’s worst enemy is a sharp object! Students learned that the rubber which makes up a balloon, consists of long strands or chains of molecules. These long strands of molecules are called polymers, and the elasticity of these polymer chains cause the rubber to stretch. The secret to this is experiment is to puncture the ends of the balloon where the rubber molecules are under the least amount of stress. Once the students discovered the secret, they could all breathe a sigh of relief!
