0:00:00.100,0:00:04.090 800...1000 0:00:04.110,0:00:08.140 0:00:08.160,0:00:12.170 0:00:12.190,0:00:16.240 Hi, Mrfixitrick here... 0:00:16.260,0:00:20.300 and today we're going to give a demonstration 0:00:20.320,0:00:24.370 of the Magnetic Drive Plasma Ball. 0:00:24.390,0:00:28.480 Here's the idea with the magnetic drive. 0:00:28.500,0:00:32.590 Okay, we've got six neodymium magnets 0:00:32.610,0:00:36.710 glued to the bottom of the plasma ball. 0:00:36.730,0:00:40.870 There are six neodymium magnets also 0:00:40.890,0:00:45.040 in the top of this rotating disc here 0:00:45.060,0:00:49.220 which is attached to a 0:00:49.240,0:00:53.430 blower motor, a 12-volt blower motor inside this contraption. 0:00:53.450,0:00:57.600 With the magnets, these six magnets 0:00:57.620,0:01:01.790 are all North-up; these six magnets are also North-up. 0:01:01.810,0:01:05.970 And when they go together, they go together in repelling mode. 0:01:05.990,0:01:10.160 And it's all controlled by remote control. 0:01:10.180,0:01:14.230 0:01:14.250,0:01:18.300 You can see that the ball 0:01:18.320,0:01:22.360 has a magnetic coupling with the 0:01:22.380,0:01:26.420 with the rotating disc here. Part of my 0:01:26.440,0:01:30.520 vacuum chamber here...It's got a 1/2 inch thick 0:01:30.540,0:01:34.630 polycarbonate base, and we're going 0:01:34.650,0:01:38.760 to put the Plasma Ball inside of that, 0:01:38.780,0:01:42.890 and it's free to rotate 0:01:42.910,0:01:47.060 in there, and just going to set that on top 0:01:47.080,0:01:51.240 of our rotating magnetic drive, 0:01:51.260,0:01:55.450 and see what happens. Ok we've got 0:01:55.470,0:01:59.630 a magnetic drive! In spite of it going through the 1/2 inch polycarbonate; 0:01:59.650,0:02:03.810 the fields have to go through the polycarbonate. 0:02:03.830,0:02:08.010 Ok, this is our experimental apparatus here... 0:02:08.030,0:02:12.230 where we have a polycarbonate 0:02:12.250,0:02:16.300 structure with a Plasma Ball inside. 0:02:16.320,0:02:20.370 The Plasma Ball is lit up currently, 0:02:20.390,0:02:24.460 and it's self-powered with 4 AAA batteries 0:02:24.480,0:02:28.540 in it's base. So what we're going to do...this is a protective cover for this experiment 0:02:28.560,0:02:32.620 more than anything else. Eventually we'll make this into 0:02:32.640,0:02:36.720 a vacuum plasma container. 0:02:36.740,0:02:40.850 But for now, it's protection. And we're going to get 0:02:40.870,0:02:45.000 a nice close-up of this thing spinning at high-speed. 0:02:45.020,0:02:49.060 0:02:49.080,0:02:53.260 I guess we're ready, so let's dim the lights... 0:02:53.280,0:02:57.460 and fire things up! Oh, one last detail.. 0:02:57.480,0:03:01.640 Safety glasses! One for you... 0:03:01.660,0:03:05.840 Thank-you. I have two observers here. 0:03:05.860,0:03:10.030 today, observing me doing crazy things... 0:03:10.050,0:03:14.210 Oh, one more thing I have to do here... 0:03:14.230,0:03:18.220 I've gotta put on my Lab Coat! Pretty snazzy, eh? 0:03:18.240,0:03:22.260 I'll just model it here, although you won't be able to see anything, but trust me 0:03:22.280,0:03:26.410 It's white. Therefore it's official! 0:03:26.430,0:03:30.460 That's what they teach us in school...wear white things, 0:03:30.480,0:03:34.540 and you can say you are official! Ok, 0:03:34.560,0:03:38.620 ahhh, lights...there we go... 0:03:38.640,0:03:42.730 It's a little wobbly, but we'll see. Oh look at that. That's pretty cool already! 0:03:42.750,0:03:46.780 We see with a little bit of spinning, 0:03:46.800,0:03:50.940 The plasma....it comes to a stop, the plasma keeps rotating... 0:03:50.960,0:03:55.150 The gases keep rotating. It has momentum! Exactly! 0:03:55.170,0:03:59.340 Ok, wheee! 0:03:59.360,0:04:03.530 That's pretty cool. so, yeah, 0:04:03.550,0:04:07.720 Yeah, it's pretty shakey! 0:04:07.740,0:04:11.910 I don't know how far we're gonna get with this! I'm just going to shut it down, and we 0:04:11.930,0:04:16.090 can watch it stop now, and it keeps rotating... 0:04:16.110,0:04:20.270 Cool! ...it also seems 0:04:20.290,0:04:24.410 the arms seemed to stay up high there, didn't they? I'll try that again... 0:04:24.430,0:04:28.460 0:04:28.480,0:04:32.500 0:04:32.520,0:04:36.590 Ok, I'm going to shut it down now... 0:04:36.610,0:04:40.700 Wheee, yes, the arms 0:04:40.720,0:04:44.790 all stay up at the top and rotate; they don't go down toward 0:04:44.810,0:04:48.950 the bottom while it's still rotating. That's pretty cool. 0:04:48.970,0:04:53.120 So what would be the speed, so far? 0:04:53.140,0:04:57.290 So far, we've only gone up to what 400 rpm or so. We're going to try 0:04:57.310,0:05:01.470 to shoot for like 3000 or somewhere in that range. See if its holding... 0:05:01.490,0:05:05.650 It's dubious that we're going to make it. I think we're gonna crash, 0:05:05.670,0:05:09.840 before that happens. If we get 1000, we should celebrate. That's ok, that's ok. 0:05:09.860,0:05:14.020 So, ok, it could just, well I don't know what it could do, 0:05:14.040,0:05:18.200 that's why we're trying it. I just have to double-check 0:05:18.220,0:05:22.400 if we are ok here, is anything weird going to happen? It shouldn't jump off the whole table 0:05:22.420,0:05:26.420 unless we have levitation... 0:05:26.440,0:05:30.470 and if that's the case, we can all jump for joy! 0:05:30.490,0:05:34.510 We'd have the cheapest levitating device yet! There I'm going to hold it like 0:05:34.530,0:05:38.550 this. 0:05:38.570,0:05:42.610 0:05:42.630,0:05:46.670 0:05:46.690,0:05:50.760 What do you have there now? 0:05:50.780,0:05:54.860 1000? Yes, very nearly 1000, 900 0:05:54.880,0:05:59.010 0:05:59.030,0:06:03.180 Look at the beam, it's amazing! 0:06:03.200,0:06:07.370 It's like it pops up all of a sudden. Wow, yeah! 0:06:07.390,0:06:11.540 see what it does...1100. 1100, Ok we'll shut it down... 0:06:11.560,0:06:15.720 Wheeee! Hmmm... 0:06:15.740,0:06:19.930 Interesting...I would have figured they would stay on the equator... 0:06:19.950,0:06:24.110 but it creates shapes, eh? Yes, it was almost an hour-glass shape 0:06:24.130,0:06:28.310 the way it looked in the camera, here. 0:06:28.330,0:06:32.500 I think we did something to it...something strange happened... 0:06:32.520,0:06:36.550 haha, poor thing! 0:06:36.570,0:06:40.620 ok, let's take it up again, let's take it up to 0:06:40.640,0:06:44.660 some sort of Vmax here... 0:06:44.680,0:06:48.730 Try to find the right rpms... 0:06:48.750,0:06:52.840 500... 0:06:52.860,0:06:56.980 0:06:57.000,0:07:01.140 800...1000 0:07:01.160,0:07:05.300 Ohhh! hahaha. 0:07:05.320,0:07:09.480 Nearly 1100 there. She popped out of her top there... 0:07:09.500,0:07:13.660 Ok, we need a pause for the cause, and regroup on this one! (clap,clap) 0:07:13.680,0:07:17.730 Yay! So far, so good! 0:07:17.750,0:07:21.830 0:07:21.850,0:07:26.010 Whoops... 0:07:26.030,0:07:30.190 Ah, the battery tray just came out and got stuck to the magnet... 0:07:30.210,0:07:34.370 0:07:34.390,0:07:42.075 Whoo!...Ok, enough of that...
