Swivel chairs
I managed to master the trick of sitting near the corner of a table, and with a swift flick of the ankle, kick the table leg just hard enough to do a complete revolution and stop with my outstretched legs just touching the other side of the table leg. Another quick flick and I'd rotate a full 357 degrees the other way (or thereabouts allowing for the positioning of my legs against the table leg.)

This took about 20 mins practice to get it just right.

The next trick was to do 2 full revolutions, drawing my legs in to avoid the table leg on the frst pass. This is harder to judge because drawing your legs in increases the rate of revolution.

Three was harder.

Trying to do 4 revolutions resulted in my booting the table over and nearly falling off the chair. Nobody noticed because I used sit in the server room a lot of the time. This was because it was quieter and warmer because the building wasn't complete and had no heating to speak of. In November.

Luckily the monitor on the table wasn't damaged though the '8' key flew off the keyboard and completely disappeared under a server rack.

that should be an Olympic sport. Well done, have a click!
