Ping Pong ball filled with Propane spins and EXPLODES

The video showcases a series of experiments involving ping pong balls. First, a ping pong ball is filled with propane and ignited, causing it to explode. The experiment is conducted safely, though it annoys a neighbor. Next, propellers are attached to a ping pong ball to test its flight capabilities, but it doesn't gain much altitude. Finally, a more explosive experiment is conducted, resulting in ping pong balls catching fire and shooting across the yard. The video emphasizes safety and experimentation, with a playful and educational tone.
