Who knew there’d be so much science behind a widdle M&M? To prevent the M&Ms from melting in your hands and leaving a (brown, gross-looking :P) mess, the makers had to take into consideration the following factors:
1: The melting point of most chocolates ranges from 16-34[SUP]o[/SUP]C. The external body temperature is about 35[SUP]o[/SUP]C and the internal body temperature is about 37[SUP]o[/SUP]C. This means that the chocolate will melt both in your hands and in your mouth immediately.
2: M&Ms do no melt in your hand because they’re protected by the crispy sugar coating which is (a) insulating so it prevents the transfer of heat from the hand to the chocolate inside and (b) of a much higher melting point than the skin.
3: The melting point of the sugar coating is so high that it won’t even melt inside the mouth. But but but, it dissolves (not melts) when it comes into contact with moisture inside the mouth (or even sweat on your hands!) because it is made up of glucose which is so soluble, unlike chocolate.

Chocolate science any time over rocket science ![]()
