It's completely useless yet awesome experiment. Combined diamagnetic suspension levitation with diamagnetic opposition levitation with lots of soap bubbles and sparks + spinning caused by a homopolar motor.
Step 1: Once You Get Things to Levitate Add Bubbles and Sparks
1. Diamagnetic suspension rig (height adjustable magnet that is leveled in horizontal plane)
2. Cylindrical diamagnetic opposition levitation device that can levitate a piece of pyrolytic graphite.
3. Soap bubbles
4. battery and wires for a homopolar motor. My power source was a rechargable 3000mAh 3,7V battery.
