Back in 2016 Rich created the 'Bi-Ball', a double sphere attached in the middle that can actually be spun on any surface, and especially works great on typical concave spin stations. You basically put it between your thumb of one hand and pointer finger of the other and give it a good flick spin. The balls spin around in a gyrating, bouncing up and down fashion and make an incredibly pleasant noise. You can get some surprisingly long fun spins with great sound effects! They're a brilliant fidget toy and so fun to play with. The is the coup de grace of the Bi-Balls, made out of pure superconductor material, which creates AWESOME patterns, so it's fun just to twirl around and look at in addition to the great spinning itself. These are VERY rare and hard to come by, don't miss it!!
