Hi Eleanor, In answer to your question, lets look at the two videos in question. Here is David Sereda interviewing Boyd Bushman: http://www.youtube.com/watch?v=VzwOFCSFms4 And here is... well, that guy I"ll call Mr. T. A. Manic explaining Lenz's Law: http://www.youtube.com/watch?v=qWu82nJS42I I"ll offer synopses of the videos in question. In the Interview video, Sereda asks Bushman if he has any experience with UFOs and anti-gravity propulsion at Area 51/S4. Bushman is unwilling to respond with anything more than a nonanswer-answer, instead asking if Sereda has ever seen "that guy Bob Lazar explaining UFO propulsion" before. And Boyd's got a sparkle in his eye and a little smile on his lips. 'sure!" David replies, like Wile E. Coyote standing at the precipice of a ledge with an ACME rocket strapped to his back and holding a lit match to its fuse. Because, to take a side road down toward bizarre-Lazar land, let's be honest here: Lazar claimed false postgraduate credentials at MIT and Cal Tech; he claimed a position at Los Alamos when it turned out he was just a technician working through a contract agency; he claimed that UFOs were powered by a stable element 115 long before it had been synthesized, when - in fact - after synthesis in 2003 it was found to be unstable with a half life of ~200ms. The guy is less credible than a cat burglar caught holding lock picks in a safety deposit vault, while claiming to the police he was just using them to scrape his nails clean. Big. Red. Flag. Getting back to the story with Sereda and Bushman... Well, Bushman replies, after referring to Lazar, "watch this!" Bushman then takes a nonconductive tube and a conductive tube (I think copper) and drops cylindrical neodymium magnets down each. Well, low and behold, down the nonconductive tube it drops, accelerating at 1g just like it ought on planet Earth. But, down the copper tube, it strangely slows down. Verrrrry weird. Sereda is quite impressed. "Wow!" And now the fuse to that ACME rocket strapped to Sereda's back is lit. But lets transition to Mr T. A. Manic's video explaining Lenz's Law. It just so happens that our T. A. Manic demonstrates _exactly_ the same phenomenon using one copper tube, one glass tube, and two magnets. Down the glass tube the magnet falls at the expected rate. And yet down the copper tube ... _whoa_ ... it falls slowly! Just like Bushman's demonstration did. Only Mr. T. A. Manic very quickly and very loudly - because he's manic - explains that this is due to a rotating current imparted to the tube by the magnet which causes a kinetic reaction. He then goes and calculates this effect across three different scenarios just so students get the idea how to apply the math behind Lenz's Law. Success in learning! _Exactly_the_same_demonstration_. Getting back to Bushman and Sereda, Mr Bushman then shows a coil wound around a torrus and places it atop a conducting aluminum plate. He applies high voltage and current and low and behold... it jumps! _Anti-Gravity_!!! Sereda is shocked! "Why, how did you do that!?!?!" That burning fuse is getting mighty close the base of Sereda's ACME rocket... _Pretty_soon_now_! JUMP CUT (the obvious question where Sereda asks Bushman to show him the effect with that electromagnet placed on top of a glass coffee table thus edited out). Sereda and Bushman move to a discussion about how Mr Bushman drilled out a hole between two neodymium magnets and then ran a threaded bolt between the two pointing at the same poles. As we know, with magnets opposites attract but the same poles repel. So, Bushman says he used nuts to screw down the magnets close together. It was difficult work. Then there was silliness about putting this contraption inside a faux rock that we"ll ignore, but which is funny all on it's own. "Well," Bushman says to Sereda, "you know about Galileo's experiment at the Leaning Tower of Pisa. Right?" "Sure!" "So I dropped my contraption and a rock at the same time and guess what happened." "Noooo!!!" Sereda replied, now flying off the ledge under the power of his ACME rocket. "Yup! The two magnets fell much slower than the rock!" "Wow!" "See this," Bushman continued, as he held out a sheet of paper with writing the camera can"t discern. "This is a paper signed by someone you've never met who will attest to the fact that he witnessed this event once and that proves anti-gravity!" "Of course! ANTI-GRAVITY!" Sereda exclaims. "My Lord, we're closer than I thought!" And now Sereda is well off the cliff and high in the air, but the ACME rocket has long since run out of juice. Sereda just hasn't realized it yet. But this is cartoon land, so, unlike in the real world, he's not falling yet. Soon enough, though, the desert ground will come and smack him with a _poof_! There concludes my synopsis of the Sereda video interview of Bushman. Which, for anyone who watches, will realize - though tongue in cheek - is reasonably accurate to the events depicted therein. --- Now I"m going to speculate. I honestly believe that Boyd Bushman was trolling a gullible David Sereda and the entire UFO community. I don't believe he's a "disinformation specialist". This is altogether too stupid for that. Instead, I think the whole thing is the kind of old-guy prank that's meant to rib Sereda and anyone else who'll fall for it. He'll forward YouTube links of the interview to his friends, showing them all those craaaazy UFO folks who take it seriously, while he and his friends, who all took undergraduate physics 101, laugh and laugh and laugh. Seriously. That's what I think. And that's coming from someone who's no professional physicist, so take it for what you will. Here's a prediction: Those magnets and a rock, when dropped at the same time from the same height, will land on level ground at the same time; within a reasonable margin of error. Betcha. And I don"t say that out of humor or with disrespect, Eleanor. -M Listen to 'Strange Days...
