About this sandbox
A 30 by 20 cm plate you can paint on: heaters, freezers, copper, glass, wood and insulating walls. Heat flows in two dimensions, cell by cell, as fast as each material allows.
Things to try
- Build a wall with a gap and watch heat squeeze through.
- Lay a copper wire across glass.
- Draw radiator fins and touch the edges to room air.
