MoMA’s spherical ice tray. My friend Duke told me about this when we had drinks and hot dogs at PDT earlier this year. Why spheres? “Spheres of ice are preferred by serious on the rocks drinkers because the reduced surface size means that the ice melts at a slower pace.” Would probably be even more awesome if you made clear ice. Will be getting these for my mom and bro for Christmas. (Dave, if you are reading this, don’t show mom!)
