Muahaahaa -- meet my next gladiator top, glow and all. The victims will put up good fights now and then, but you know what's gonna happen eventually.

I saw this around last week or so. The big top completely annihilated the beyblade top(and the other ones for that matter). Luckily no one got hurt by the beyblade shooting off so fast after being hit(could have easily knocked out a tooth or put out an eye). These videos of things melting things/smashing things to pieces are very intriguing because I personally would never attempt such a thing in fear of loosing a finger(or getting burned very badly).

At the end, the guy said that they should really be using a taller metal safety enclosure, and I agree.

To me, the most amazing thing about this video series is that the woman seems to be as much into these guy stunts as the guy. At first I thought, "Why can't all wives/girlfriends be like that?" But that would be the end of human civilization, because then there'd be nobody to save guys from themselves.

I agree on both counts. This experiment has the potential to be deadly.

A very surprising top behavior is what happened at 8:10 (slow motion at 9:02) when the top changes its spinning axis.

That caught my eye, too. Immediately started thinking about how to make that happen in LEGO. Might even be doable given that it works with a spoked rotor. Guessing that the rotor's roughly isometric symmetry in the video made it easier for the spin axis to flip from the stem to one of the spokes and stay there for a while.

Really love their slo-mo sequences. The balloon filled with glitter was sheer video magic! The evolving air flows made visible by the glitter tracers were absolutely mesmerizing.

Everybody has an inner physicist, and a good one at that. Often, all you have to do to get in touch with it and tap into its expertise is to give it a really good look at what's going on. High-speed video is great for that.

good vid, Thanx...

"all you have to do is to give it a really good look at what's going on."

this statement can be applied to many different topics:16th century poetry comes to my mind; about John Donne's works, I tell the students to READ

Not exactly a top due to the hydrostatic support, but close...

This Finnish couple clearly loves rotary motion as much as we do. They're just better equipped than most of us and sometimes take it in different directions than we usually do. Would love to go visit them and get in on some of the fun.

Oh my!!! That is some crazy stuff. I suddenly do not feel so warm today.

These people do some dangerous stuff lol. Luckily I live in Alabama and we don't see frozen lakes too often here. Crazy. I would not have the guts to do half the stuff they do, one slip and I'm gone x_x
