PSA - Beware of Ping Pong Balls
Lesson from science today - ping pong balls are highly flammable.
I was supposed to be demonstrating potential energy and a push-pushes back type of thing. I ended up demonstrating that sometimes science experiments go awry, and I need adult supervision while doing them. :)
No wonder, my college lab professor stationed me under the fire extinguishers.
The experiment today called for pushing pencils with a clothes pin and using a string as a trigger. The idea is that you tie the clothes pin open then burn the string and make a trigger which releases the energy and launches the pencils. I thought ping-pong balls would be more dramatic than pencils. Well, they were. Science is exciting around here.
