Mark Hayward has invented several spin top tricks, but this is the one he’s most well-known for in the spin top community. Yes, that’s a real thing.
1) You can only do this trick with a top that has a totally smooth low-friction surface (no tape), and doesn’t have anything dangerous like the Duncan string groove, or crown tabs that can catch your fingers.
2) It’s WAY easier with long nails. Depending on your finger shape and skin stickiness, it may not be possible to do this trick without nails.
