Simple experiment
|
' A little experiment showing the importance of reflection as an insulator. We filled three tea pots with 600 cc boiling hot tea 1) Pot on the left is made of steel but has an enamel coating. 2) Pot in the middle is made of stainless steel with high reflective capabilities 3) Pot on the right is made of ceramic
Even after four (!) hours we could see and feel that the tea in the stainless steel pot is still warm
