    I once touched an experiment in the form of a metal wire coil where each alternative loop was hot and the other cold. It felt superhot instead. I feel like this would be similar.

      You can recreate this with sausages or some cooked vegetables. We do it at science fairs.

      Set them up in an alternating pattern of cold, hot, cold, hot. Let somebody place their arm on top. They’ll feel like they just got a severe burn, even though they’re fine and the sausages are not hot enough to cause any harm.
