Light Sensitive Color-Changing Vampire Slime
Vampires – the best slimers in the world!
Vampire Slime looks and feels like the same high quality slime that our customers have come to trust, but something is different! Vampire Slime turns from eerie GREEN to blood RED when you hold it up to the light. Maybe that’s why we call it Vampire Slime!
Here’s the secret…
Vampire Slime contains a dye that actually creates a unique special effect. At most angles, the slime absorbs all light frequencies except green, which is why our eyes see it as green. But light passing directly through the slime appears red because the special dye is absorbing all of the light except for red.
What does it teach?
Slime can be used to introduce the concepts of chemical bonding, the cross-linking of molecules, and the properties of polymers. Students can literally feel how the cross-linking agent goes to work linking together the long chains of molecules that make up the polyvinyl alcohol solution.
