Skate On Anything

 Ice skating on any surface that can fit inside a centrifuge.

Ingredients: 1x Centrifuge, large enough to hold a skating rink full of people. 1x Pair of ice-skates, blades preferably made of titanium. 1x Full-body brace, capable of preventing a body from collapsing under increased 'gravity'.

Now, hop in the 'fuge and spin it up to speed. Ice skating works because the skater's weight causes the skate blade to put pressure on the ice, melting it. The skate glides over this melted layer. The increase in weight experienced by skaters in a centrifuge will be enough to create the same effect on virtually any surface one cares to skate on. Solid rock, steel plating, plate glass, Schwarzenegger's bicep, frozen custard - the list is far-reaching.

The rink would need resurfacing more often than an ice rink, as grooves in the surface would not re-freeze (albeit only a small amount of water on an ice rink surface refreezes anyway).

Skate on anything? Why not a popsicle? [Letsbuildafort, Oct 10 2004]

Ice skating doesn't work because of the pressure, so the basic tenet is flawed. [m homola, Nov 06 2007]

Water... http://www.lsbu.ac.uk/water/phase.html
.. is far more complicated than I thought (the rest of the site is good, too). [neutrinos_shadow, Nov 06 2007]

       This gives me an idea.

       Then my work here is done.

       I like to skateboard everywhere, Here's what I do. 1. get thrift store rollerblades. 2. take wheels off. 3. put them on skateboard. V-walla you now have a skateboard that has light weight wheels and the diameter is increased allowing you to more easily travel across Arnolds Arm, or my FAVORITE! ... packed dirt nature trails. Skating takes a lot of indurance so probably hesitate, unless you are already a champ. sorry to go off on a tangent but I'm a fanatic of transportation that does not break. That is why I like your idea. Titanium. yeah.

       This idea reveals an in-depth ignorance of the properties of water, ice and other substances.   

       Water is one of a very few substances which expand on freezing. For this reason, pressure lowers its melting point.   

       Almost all other substances contract when they freeze. Therefore, increasing pressure will inhibit, rather than encourage, their melting.

       Thanks [MaxwellBuchanan], that makes sense.   

       Also, [vigilante], your metal ice skate blades would be dulled by hard surfaces such as hard rock or frozen custard. Bone!
