Heat is flowing from your hand into the ice cube. When you touch an ice cube, the heat from your hand is transferred to the ice cube, causing the ice cube to melt. This transfer of heat from your hand to the ice cube makes your hand feel cold. Additionally, the ice cube's temperature is lower than that of your hand, so as heat is transferred, it feels even colder in comparison.
