Magnetic Putty: When Super Magnetic Thinking Putty is stretched, molded, or shaped, the putty has no magnetic charge and behaves like any other Thinking Putty. However, in the presence of a magnetic field, its magnetic forces begin to align. Suddenly, a truly Super Magnetic Thinking Putty is created that will attract to one magnetic pole and repel from the other. You"ll also find a super strong neodymium magnet in each of these tins. Crystal Clear Thinking Putty is completely clear! Its consistency is a bit different than our other Thinking Putty, but it is AWESOME and as clear as glass. Glow in the Dark Thinking Putty is hypnotic and irresistible! Milky white in daylight, their glow magically appears when the lights dim. You can use our Blacklight Keychain to write messages on the putty and draw special designs. You can even do cool tricks with Glow in the Dark Thinking Putty. After exposure to light (the brighter, the better), these colors will glow for hours. Super Illusions Thinking Putty colors are brand new colors unlike any we have ever made! Crazy Aaron worked for years in his basement lab to come up with these mystifying colors. These truly original colors will blow you away and keep you playing for HOURS! And, while room lights are great, sunlight makes these colors really EXPLODE!
