I Think I Learned: Teacher Demonstrates The Marble Tracks He's Built To Teach Physics Principles

November 8, 2017

This is a video of Pennsylvania physical science teacher Bruce Yeany demonstrating a bunch of the marble tracks he's built over the years to teach students various physics principals. I thought it was a great refresher course in basic physics. And by refresher course I obviously just mean fresher course because I did not know any of those things. Did I even learn physics in school? SPOILER: No I did not, because I was out the whole semester with mono from kissing girls on the playground. "He licked the monkey bars." IT WAS A SWING SET, MOM.

Keep going for the video (but feel free to skip around to see the various tracks) while I say a silent prayer everyone here is refined enough to not leave a playing with your balls joke in the comments.

Thanks to Nat, for inspiring me to want to be a teacher and spread my vast wealth of knowledge to today's youth.

    This is cool. I'm saving this for the kiddo. I love inspired people doing what makes them happy - they really add so much to the whole life thing.

    My physics teacher never let me play with his balls....

    I learned something new today. Favorite one was the two identical curves "race". I didnt expect the height released to have no impact on winning the race.

    My physics teacher never let me play with his balls....

    I had a chemistry teacher who always put the best looking girls at the front of the class. Pretty sure he would have been open to let a few students play with his balls.

    That's awesome. My science teacher was an angry old man that tried to yell information into our skulls.

  • Draco Basileus

    Sometimes I imagine Galileo swinging his balls around in public. That's why the Pope locked him up.

    How to make history and science fun without a extremely long tedious video. +1 for the guy's enthusiasm, but this feels like i'm back in the 90's.

  • Jeremy Tilton

    Always with Galileo, these Physics professors! No one ever talks about the fantastic discovery of Bob Smith, a guy who, baffling scientists, fell up the stairs back in 2000.

  • GeneralDisorder

    Bob Smith didn't invent falling up the stairs. Hell, I remember doing that in the mid 90s.

  • Jeremy Tilton

    Yeah, I sorta do it every weekend after a few drinks.

  • steve holt

    I actually laughed out loud.

    Sorcery!
