use it: cool stuff round-up

Lately I've been trying to stay better hydrated in order to have more energy, and I've taken to drinking my water with a ton of ice. Sometimes I wish there was a way to make the ice water a bit more interesting. Conveniently enough, every now and then while perusing Pinterest, Tumblr, or the web in general, I come across some products that are just plain neat. Over time I've found a bunch of fun ice cube trays and molds. Here are my favorites:
