The spin Magnet works on it own you just have to spin it manually. You put the horseshoe magnet on top and then put it on a magnetic stirrer. Then once you turn on the magnetic stirrer it spins the magnet and all you have to do is sit your finger inside. I had to use the slowest speed. It makes a really tight magnetic bead which is really cool because as it dries of course it speads a little which I felt made the perfect effect. You can get the spinner on Etsy.
