Details: Special instant worms that contain a thermochromic magenta color-changing dye. When the Spangler Labs team came up with Insta-Worms they were an insta-hit. There's nothing better than having a bowl full of worms without the hassle of digging them out of the ground... and all by using fascinating polymer science. Now our worm-ologists have made an exciting new kind of Insta-Worms that are heat sensitive! You won't believe your eyes as temperature changes the appearance of this special kind of Insta-Worms. You just squeeze a stream of the special magenta Heat Sensitive Worm Goo into a bowl of Worm Activator solution and... wow! Just like original Insta-Worms, the liquid becomes a solid that resembles - you guessed it - a worm! This special worm formulation also holds a secret. When the worms reach a certain temperature, they lose their color. That's crazy! Do you miss your colorful worms? Stick those stringy, slimy little guys into cold water and watch them change back to magenta.
Features:
- A great introduction to the chemistry behind polymers
- When the Worm Goo comes in contact with the Activator, the goo immediately changes from a liquid to a solid
- We've added a special dyes to our worms including temperature reactive Blue & Magenta, Glow in the Dark, and Vampire Veins that change from Green to an eerie Red under a Black Light.
