Musca Domestica (commonly known as a housefly) has thousands of individual visual receptors called ommatidia. These receptors create what is known as a compound eye, which is capable of an almost 360-degree view and incredibly speedy sight. Named for the creature with the fastest vision in the world, Super Fly Thinking Putty® will put your eyes to the test! Shimmering tones of metallic green and black give way to gray and silver, just like the body of a common fly. But look again and you’ll see tones of peach, mauve, and pink refracting off of its pearly sheen. Thinking Putty® helps build hand and finger strength through a fabulous tactile play experience with unique, unexpected properties and provides relaxing, yet stimulating interaction for anyone with sensory integration issues. Crazy Aaron's putty is non-toxic, won't dry out, and won't leave a sticky or slippery residue on your fingers, so it's great for stretching, molding, bouncing, tearing, popping and playing by kids and adults alike.
