Ever had a splitting headache? You know the feeling: all your stress has gone to your head and the only thing you want to do is rub your temples and massage your cares away. Thankfully, you can do just that with the Giant Brain Ball. The Giant Brain Ball is a stress toy that is shaped like your very own grey matter—ahem, pink matter. Whenever you're feeling tense, just squeeze this squishy cerebellum and let your train of thought run off the rails. If the day is especially rough, dig into the cortex to glimpse its gooey red insides. However, the decorated outer layer is thick enough to prevent any leakage, so you won't have to worry about cracking this cranium open. Just relax and let your hands knead your stress away while your real mind wanders.
