Teacher charges himself with static electricity using a Van de Graaf generator holding paper cups on his head. The cups pick up the same electrical charge from his body. Since objects with same charge repel, the cups explode outward in all directions

      Him check all their reactions without moving his head and his cute look is so awesome lol

      We have a difference of opinion where it comes to the definition of “explode”

      Never had teachers like this doing experimentation live, but thanks to internet in can enjoy it now

      I love when teachers make learning so much fun for kids. They’re so excited.

    5. If only I had him as my teacher I would pay more attention in class instead of being an average students in all my science class.

      I’d offer a slight correction to the title’s last sentence:

      *Since objects with same charge repel,* ***the students’ minds explode*** *when the cups shoot off in all directions*

      This is how you turn science into an experience. The students will remember this demonstration and probably a lot of them will remember the underlying science about charges and similar charges repel.

      Edit: spelling correction

      I had a chemistry teacher like this in high school. One of my favorite demonstrations was when he made a fireball in class from a lighter and a mouthful of baking soda (or powder, I can’t remember).

      That’s super cool! What are those metal spheres called? I used to know but I’ve got the memory of five goldfish taped together and four died.

      I love the experiment. But I don’t think you went to school long enough to know the definition of an explosion

    10. When we tried this in our physics lab in Dublin, Ireland, it failed miserably. It’s almost never not humid there, so the charge does not build up. I was a very disappointed student.

      My first degree was in physics and we had a professor that loved this device and obsessed with it, and so we did so many crazy experiments with him as a class.

      One of them was forming a chain of people holding hands away from the central point person that was touching the Van de Graaf orb, and the last person held a neon light tube, and it would actually light up!

      However, as we learnt the hard way, be warned!

      ——————————–

      Essentially:

      One fateful class when we were forming our human conductive chain for another experiment that looped around in a semi circle, the person at the other end touched the metal chalk tray below the chalk board. (You know that long tray that holds the chalks and erasers.)

      And whelp… Ya, that was slightly painful for everyone in the class!

      The moment he made contact with the far side of that metallic chalk tray… Ya… A sudden jolt of electricity surged through the entire human chain of the class, and I kid you not:

      We all simultaneously yelped, and several of us even jumped up into the air!

      ——————————–

      It was insane.

      We were all looking at each other afterwards in… shock… (pun of course intended!)

      And we were like, “Dang that hurt!”

      But even that was still a lot of fun. After our initial… “Shock”… We all started laughing and were like, “Sheeeeeeeeeit! That was crazy!”

      It was one of my favorite physics lecture classes ever! (As I said at the time, “Whoa! That was so… Metal!”)

      It really taught me a lot about respect for flowing electrical charges, I’ll tell you that!
