The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
It was pretty neat. around 23:00 I volunteer to go up on stage. He took another kid up too. He gave a tube light to her to hold in her right hand, a tube light in her left hand which I also hold with my right hand, and a tube light in my left hand. Apparently he was demonstrating the skin effect. He said he ran 50kHz through us, and the little device that he used to produce the current actually sparked, even though the video doesn't show it. But I found out that night after coming back, 50kHz is not enough to trigger the skin effect. Could he have misspoke? Maybe he meant MHz. Or if it was kHz, isn't that kind of dangerous to be letting audience members come up and let him run a current through them to light tube lights? At 33:00 around, he pulls out his SSTC. One of the workers come up and starts playing Twinkle Twinkle Little Star on the MIDI piano. She said it was Bach, no, it's Mozart actually. Anyways, at 34:00 around, you start hearing me singing to the tune. I am sorry about my singing, have you ever tried singing loud enough to hear yourself when a coil is being operated and you have about a gallon of adrenaline running through you? At around 35:00, he brings out a larger coil. He said it was VTTC, but it was a lot louder than solid state, and aren't VTTCs supposed to be quiet? At the end of the show I asked him some questions, and he showed me the coil, and it had a spark gap, so it couldn't be SSTC or DRSSTC. It must have been SGTC because it had a spark gap and it was loud as heck. I still don't understand how people think it's loud. I could drown it out with my cheering! He ran it a second time, but that time he gave the front row some tube lights to hold. I was sitting in the front row, so I got to hold the tube light again. I was surprised at how far the field reached. I was staring more at the coil itself and not the lights because the light I can do at home, my coil is enough to make it glow, but it doesn't spark well. So I was staring at a Tesla Coil for the first time in reality, not YouTube videos. I was very, very happy. I almost forgot. right around 30:00, 8 foot tall Van de Graaff. Four little kids went up on stage. On the Van de Graaff, pie tins were stacked, and confetti was hidden under each layer. It was so funny to see them being pelted with the pie tins and confetti. The one girl up in front with the black hair, her hair started standing on end so much, it was hilarious. Then he took his big grounding stick and started sparking from the Van de Graaff. This is visible to my camera, unlike the girl's hair on end. At the end of the show, I found out that Steve Ward helped the guy, Branden, to build his coils. Also at the very end, a cute kid comes up and asks the lady for a marshmallow. I laughed. But before any of you start posting comments on how I need a tripod or how I was able to tape myself, One, tripods, I am not trying to take a still shot where I expose the camera for three seconds to try to get a clear shot of lightning, which then at that point I really wished had a tripod (I still was able to photograph SOME lightning), with my dad's expensive Canon, but I m trying to video tape a show in which it really isn't necessary to hold a camera still. Even so, it was with a 2 megapixel camera, so it really wouldn't increase quality much. How I was able to tape myself? Easy, I kindly asked the man next to me to record it for that moment. But anyways, fast forward in about 7 minutes to start the show. Of course, if you have an extra 40 minutes on your hand, then...
It was really fun for me!
