Science staples involve things that go boom and things that blast off. With the Ping Pong Popper kids’ science experiment, you’ll take both the booming and blasting to new, hands-on levels. You get to construct popper toy and learn about combustion!

In case of a fire inside the filler, cover the hole with a plate or similar object.
If you take ball out of the popper, you get to witness what was happening inside.. combustion! That handy little spark igniter serves its purpose by igniting the vapors from the rubbing alcohol inside of the popper.
When the rubbing alcohol vapors are ignited, the resulting combustion causes the air inside of the popper to expand rapidly. The rapid expansion looks all over inside of the popper for a way to relieve all of the air pressure. When the air pressure finds its way out, this is called the point of least resistance. In this case, the point of least resistance is the seal between the ping pong ball and the popper
Now, the ping pong ball is squeezed into the popper pretty tight, so it takes a lot of air pressure to pop the ping pong ball. This is due to friction. Once the air pressure exceeds the necessary force to overcome the friction, the force blasts the ball off and away!
