This is my idea for a levitating pot holder. The idea is that the pot does not touch the supporting surface in any way. This keeps insects from crawling into your food. Combined with a lid this would be perfect for picnics or anywhere bugs are feared. It would also work well as a serving holder for any dinner table center piece or casual dining.
The magnets would be natural magnets and at minimum three would be required however I'm not sure of the size required to make the correct gap and what the weight limit would be.
