This little red heart is a useful gadget that gets your hands warm. It needs no external power. All it depends only the clever liquid that is filled inside the little red heart and a little metal switch.
When the metal switch is clicked, the liquid solidifies and heats up, and it’ll become useful in the cold winter night, to keep your hands warm or shove it anywhere that needs warming. You can get it from IWantOneOfThose for only $5.54. But we’re little too late for the Valentine’s.
