COEUR d’ALENE — Science is everywhere.
Modern-day wizard David Hagerman made this joyfully apparent Thursday as he showcased his scientific sorcery to wow students at Bryan Elementary School.
The Emmy-nominated David Hagerman generated laughter and wonder as he used gravity, electricity, chemical reactions and humor to share just how cool science can be.
Audience volunteer Jasper Myers was impressed when his pink hair stood straight up as he placed his hand on Hagerman’s Van de Graaff generator, a device that produces static electricity.
“Nobody else’s was,” the third grader said. “It was fun, I’ll say that for sure. I loved it.”
During the second of two high-energy assemblies paid for by the Bryan Parent Teacher Association, Hagerman shared that his first favorite thing is that he appeared on “America’s Got Talent.”
“My second favorite thing is that I perform at NASA,” he said. “When NASA needs entertainment, they ask me to do it.”
His third favorite thing is that a popular meme has been made out of a humorous clip of him on YouTube, known as “Make Sure It’s on Low,” when his bald head gets what appears to be an accidental zap from a Tesla coil, complete with a zapping noise.
“Because it was a Tesla coil, it had very low energy, so I’m still alive,” Hagerman said.
During one demonstration, he discussed the difference between slow- and fast-moving gases as he used a hair dryer, then a leaf blower to levitate beach balls.
“If I angle it, it goes up even higher because more rapidly moving air goes over the top of the ball,” he explained.
In another demo, he soaked a rag in water and methanol and lit it on fire without burning the fabric.
“What you saw burning was the methanol,” he said. “What do you think was protecting the towel? The water. Here’s why: Fire needs three things in order to burn — you need fuel, you need heat and you need oxygen. The oxygen bonds to the fuel and that releases a lot of heat. That heat gets even more oxygen to bond to more fuel which releases more heat … It’s a cycle. You can stop that cycle by removing any of those three.”
Third grader Miloe Stern was one of several audience members called up to participate in a cup-stacking speed challenge as Hagerman used a vortex cannon to knock over the towers. Miloe said the Van de Graaff generator experiment stood out to him.
“Static electricity, how it can face multiple bodies at once and still power things, flowing through multiple bodies at a time,” he said.
Hagerman has spent more than 25 years traveling the country inspiring children to explore careers in science and technology.
“I believe that if we make science as entertaining as possible, these kids will want to study it,” he said.
