This Link2 seems to be using the same idea as a rail gun to make an uphill river!

Thanks guys for posting it all! It's not over by any mean! I've gathered over 40, practically anythyng I found worth on youtube.

I showed lots of vids with great reception; among most liked were large ferrofluid, large tesla coils and hot-opening disconnectors among other things. They were already eager to replicate ''resonantie'' (small 2W function-generator speaker just didn't have enough power) and tin-can induction motor smile

Still I have exhausted better videos to some point, and I would appreciate anything you post...

I think pulsed power hasn't received enough attention... those slow-motion's are cool, but not
very clear to everyone.

I have coin shrinking scenes but not the coins, and nobody could figure what's happening unless I explain it all myself.

Can crushing as well. I can't believe no one of all you can crushers hasn't filmed anything, or I just can't find/remember those? I'm sure TDU has some more videos I can't find anymore.
That one with his son firing a CC?
Just blowing up stuff anyone? (I've already seen apples and potatoes).

Other things we would like to see are some of those high-power distribution circuits (that's what we learn there about mostly).
Fuses, transformers, switches/reclosers, disconnectors in action, more generally informative stuff I haven't found closely enough!

Acoustic Levitation

This is a pretty cool approach at levitation, no magnetism involved (apart from the speakers). I wonder how complex it would be to setup, I haven't found any hobbyist pages on it yet.

Guys, as of now I've shown like 100 videos and pretty much depleted the resources. I can post some of them if you guys are interested into a specific topic...

I guess all I could use now are videos that haven't been on web yet... there are things I may have not ran into, but not much.

Next thing we are poking into is Tim Hunkin's SLOM as it has gone open source.
