“What Happens Next?” showcases an array of mentally stimulating and thought provoking demos with discrepant outcomes.

Here’s another one:
One ice cube is placed on a metal tray (which feels cold to the touch) and another ice cube is placed on a plastic tray (which feels warm to the touch). Which melts first?
