Atomic Slime is perfect for Halloween demonstrations and parties.
Don’t worry about the explanation of how Slime works until you’ve made the perfect batch. Atomic Slime is formulated with a special coloring agent that fluoresces under black light. The eerie, greenish-yellow glow makes this slime irresistible.
- Bottle of Atomic Goo
- Cross-Linker solution (included in all of our slime kits)
- Mini black light (optional)
- Plastic cups
- Spoons or stirring sticks
- Zipper-lock bags
- Paper towel
Measure 2 ounce (60 mL) of the Atomic Goo solution into a plastic cup/bowl. If you have the Shaker Cups – it is marked with ounces on the outside for easy measurement.
Add 1 ounce (30 mL) of the Cross-Linker solution to the Atomic Goo in the cup.
This is the last step – and the most important one. You can choose to shake or stir! If you have a lid for your container, shake it up – keep shaking for at least one minute. If you don’t have a lid, then no problem, just use a stir stick or spoon to mix it all together. Keep stirring or shaking until your liquid is not a liquid anymore. It should be a big clump of slime!
If you want to make a larger portion, use the lines of the shaker cup or keep these same proportions for a bigger batch. To make two ounces of slime, you need two ounces (60 mL) of Goo to each two tablespoons (10 mL) of Cross-linker. It’s that simple!
The beauty of this recipe is that you can adjust it to just the way you like it. If you want slime that is less “slimy,” just add a bit more Cross-linker. Want more “slimy” then add less.
As an added bonus, shine the mini black light onto the blob of Atomic Slime… and look at the eerie greenish-yellow glow! You can also prepare the mixture under a strong black light (like the ones found at Halloween). The mixture will have a radioactive glow that is guaranteed to produce a room filled with ooohs and ahhhs!
How Does It Work
Slime stretches in a most unusual way. If you try to stretch slime quickly, it will literally break in half. If you stretch the slime slowly, however, it will get longer and longer and longer. Why? Scientists consider slime to be a “Non-Newtonian Fluid” which means that it behaves like both a solid and a liquid at the same time. When you apply pressure, it turns into a solid (so to speak) and breaks apart. When you let slime flow like a liquid, it stretches with no problem.
Most liquids, such as water, are made up of small, unconnected molecules bouncing around and tumbling over and into one another. These single, unconnected molecules are called monomers. Monomer liquids flow easily and are seldom gooey or sticky to the touch. In other substances, the monomers are linked together in long chains of molecules known as polymers. These long chains don’t flow easily at all. Like a bowl of cooked spaghetti, they sort of roll over and around one another. Liquid polymers tend to be a lot gooier and flow more slowly than liquid monomers.
PVA (polyvinyl alcohol) is used by the plastics industry to form surface coatings and to make surface films resistant to gasoline. It’s also used to make artificial sponges, hoses, and printing inks. If you check out the ingredients of contact lens wetting solutions, you may find PVA used as a lubricant and a cleanser.
