I dont see how it wouldnt make the ice melt faster, I forget the scientific terms and such but heat energy transfers from the hot to cold, or rather the cold absorbs the heat energy? So the cup/liquid should be absorbing the heat from the puck, even if its slightly warming the liquid its going to melt the ice faster. but then the ice should be keeping the drink itself at a constant temp, theoretically in a perfect environment? Idk, theres a reason I'm not a scientist
I really wanna give this thing a whack but I might wait a long while before jumping in. Gotta see how it plays out and what they come out with. I think one of those insulated cups would have me sold after the bugs and stuff gets worked out...which I fully expect them to iron it out quickly
