KENTUCKY (7/6/17) We all know sharp objects and balloons don’t go together.

INGREDIENTS

  • Skewer
  • Balloon


INSTRUCTIONS

STEP 1:  Blow up the balloon, let some of the air out of the balloon, and then tie a knot at the end, to hold the air inside the balloon. Describe the balloon by using its observable properties.  
STEP 2:  Gently twist the skewer into the thick part of the balloon, near the knotted end. Continue to slowly push the skewer through the balloon, until you push the skewer through the thick end of the balloon, opposite the knot, stop, and observe. Explain how the balloon can be used as a model to describe that matter is made of particles too small to be seen.

EXPLANATION
The balloon is made up of polymers, which are a bunch of molecules linked together, to form long chains. These long chains link up around the skewer, keeping the air from escaping.
