Light Sensitive, Color-Changing
Explore the science of building polymers by cross-linking long chains of molecules
Veins are an important part of the human anatomy, but did you know that vampires need veins to transport all of their blood, too? It’s true. Vampire Veins are way different from human veins, though. You probably know that veins and arteries appear red or blue in humans. But, that’s not the case for vampires!
Vampire Veins are a creepy green color and, if you look closely, you’ll see that these eery veins have blood flowing through them! Well‚ not really. Instead, Vampire Veins contain a special dye that reacts to light in different ways. But the secrets don’t stop there… turn off the lights and switch on a black light. Great jumping Draculas! Vampire Veins are fluorescent, too! Try not to scream as you learn how to create Vampire Veins and discover the science behind them.
How does it work?
Vampire Veins String Slime works through the magic of polymers. Although String Slime starts as a liquid, through polymerization (the formation of polymers), the liquid becomes a solid and looks just like a string. Vampire Veins also feature a special dye that reacts to both regular and ultraviolet light in different ways.
What does it teach?
Young scientists will explore the science of building polymers by cross-linking long chains of molecules while also learning about the amazing dyes that are contained.
Vampire Veins are Way Different from Human Veins
Vampire Veins are a creepy green color, but if you look closely, you’ll realize that these eerie veins have more than a few secrets.

My kids, 1st and 3rd grade loved this kit. We’ve played with the regular worm goo before and loved it. But since the vampire veins stay liquid on the inside, we loved squeezing them until the laid eggs. Even just observing the jar of vein goo in bright sunlight was interesting. Had fun with the hand held black light also. Gave us a chance to learn about kinds of light outside the visible spectrum.
We’ve purchased many items from spangler science and loved them all.

Not only do the students we work with LOVE the vampire veins, so do the instructors! Totally awesome. The squeals of delight should be recorded. I purchased them when they were the Deal of the Day to give them a try. Would love to continue using them but they are rather expensive. I would like to see just the vein goo for purchase seperately, omiting the cross-linker and black light. This would make it much more doable for those who work in schools and non-profits.

I used this for a lab with my 7th grade students. They compared physical change vs. chemical change. It turned out to be a fun and memorable lab. It was a great start to my chemistry unit. I purchased 1 kit and I was able to complete the lab with 6 classes and I still have plenty left over.

I use Steve Spangler products in my program constantly. The Vampire Veins is one of the favorites with the kids and with me. The first time, I was so excited with the results, the kids almost didn’t get the activity our of my hands! Steve Spangler products makes me look like a genius! (or at least, very cool, in the kids eyes!) Thank you Steve!

INSTA-WORMS – VAMPIRE COLOR-CHANGING
Hi Steve,
I will be starting my Light unit with grade 1, How can I use INSTA-WORMS – VAMPIRE COLOR-CHANGING as an introduction. The students will enjoy how it works when black light closer. How can’t use INSTA-WORMS – VAMPIRE COLOR-CHANGING in my light unit as an introduction is what I mean.

Different materials and consistencies absorb light differently. The incredible thing about Vampire Worms is the way that this is demonstrated. The wave length associated with “visible” light is longer and is only able to illuminate the outside of the worm – so you see green. The wave length of UV is very short in comparison and as a result it is able to penetrate deeper through the worm to reveal it’s eerie red inside.
