Science with a bang

Boomer has a new approach to teaching, "anything that makes a bang or a noise is good".

One day the cops showed up as a result of a half-baked Boomer stunt. He was testing whether a 1.5-million-volt Tesla coil could shoot a spark across the room. In the process, he cut off all police radio communications for miles.

Boomer’s reaction: “Neat!”

Would you have liked him as your science teacher?

The balloons filled with hydrogen the students got by combining hydrochloric acid and zinc in a flask pops and creates a small fire ball, eliciting screams from some of the kids in the class.
It’s a lesson on mini-Hindenbergs, complete with Led Zeppelin’s “Stairway to Heaven” in the background. --[Excerpt from Naples News]
