2-in-1 Silicone Ice Mold
Man this one went viral. But you've got to be honest, it really is a must have item in every freezer. For those who don't know what this is: So you basically fill the outer edge with water and let it freeze over night. When you need it you just remove the cover on the inside and squeeze the mold. Satisfyingly all ice cubes automatically drop into the middle from where you can either take them out or put your favorite drink inside. This is genius!
