Brain shaped ice cube trays. Isn’t that all you need to know?
Nine bucks will net you this silicon mold that makes four ice cubes (though I guess “ice spheres” would be more apt) shaped like tiny little brains. ThinkGeek, who sells this awesome little doodad, suggests using them as novelty items at a zombie-themed Halloween party, or as an inside joke for all the nerds you work with at the science lab.
That’s not really thinking outside the box, though, now is it? Come on, let’s exercise a little creative thought. (Yes, that was a carefully-placed and intentional pun. You should know by now that I have no shame.) How about using them for jello shots at your college graduation after-party? Or put a popsicle stick in them and give kindergartners a tasty object lesson?
Hmm, somehow that sounded very sweet and innocent in my head.
Alright, okay… you should probably just stick to the zombie thing.
