- Three (3) alimunum baking pans
- Six (6) 6×6″ ceramic floor tiles
- Ten (10) 6×6″ slate floor tiles
- Nineteen (19) 1″ (long diameter) hexagonal yttrium-barium-copper-oxide high temperature superconductors
- One quart (1 qt.) Low temperature epoxy
- Several liters liquid nitrogen
Combine bulk superconductors, epoxy, and one tile (material of your choice) in baking pan. Fill with LN2 until mixture is just submerged. Experiment at 77 Kelvin till done.
