Vampire Color-Changing Slime
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 color-changing 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.
Slimy Polymer Fun
Science does not have to be boring when young students can make delightful, creepy vampire slime with the Vampire Slime Science Kit from Steve Spangler Science. This fun experiment lets children create their own slime by adding a polymer cross-linking agent to a polyvinyl alcohol solution. They can watch the slime come to life right before their eyes as the carbon atoms in the alcohol bond together to form the polymer chain. Then, once they’ve been slimed, they can watch it change color from green to red when exposed to light. This can give them a sense of how materials like the color changing slime will appear to be the color of light that is not absorbed, but is instead reflected. The Activity Guide that is included helps the children to focus on specific activities they can do that will help them to explore the properties of light as well as those of polymers.
