Safely demonstrate combustion by performing the “ping pong popper” micro-scaled explosion! Students will love the loud “pop” as a spark ignites alcohol in a popper and a ping pong ball launches 20 feet across the room. Use this eye-catching demonstration to teach both combustion and piezoelectricity. Enough chemical is included to perform the demonstration more than 25 times! Teacher Demonstration Notes included. Color may vary.
Concepts: Combustion, piezoelectricity.
Time Required: 15 minutes
