Learn about how spreading heat across a surface can make it more durable.
~20 mL warm water
Test tube holder
Alcohol burner + lighter
1. Blow up balloon and tie off. Pinch end of balloon knot with test tube holders.
2. Light alcohol burner.
3. Hold balloon to flame and record how long it takes for the balloon to pop.
4. Fill next balloon generously with water, blow up, tie off, and clip to test tube holder.
5. Hold balloon up to flame and record how long it takes to pop.
The Science Behind the Reaction
The water in the balloon spreads the heat out over a larger surface of the rubber so that the rubber is not broken down by the heat, allowing the balloon to stay intact.
See if boiling hot water or freezing cold water in the balloon impacts length of time the balloon stays intact.
