Round Spinning Objects

From RSO:

“Inspired by the coolest trick of it’s time.

The UFO trick was one of the first tricks we all learned back in the day before unresponsive return tops were a thing.  It wasn’t only visually stunning to see the return top flipped sideways spinning like a “flying saucer,” it was how you managed string tension. 

Although all return tops spin, there is only one Round Spinning Objects.”
