Yes, your mind plays tricks on you. But we prefer to call them magic tricks. This science kit makes games out of what we see, and what we don't: Double-meaning illusions like "Face or Vase?," a DIY piggy bank that makes your money disappear, and special color spinners with hypnotizing powers. (We kidů or do we?) With more than a dozen activities, it's a great gift for imaginative young scientists, and adults who want to have their mind blown, too. Ages 6+. Made in China.
