How to Make Slime With Glue

The well-stocked back-to-school section in most stores means one thing to most kids: The Elmer's glue shortage is officially over!

In 2016, school glue became a hot commodity when the "slime" craze hit classrooms across the U.S. With a simple mixture of glue, water, and a few other ingredients, kids can create a textured blob that's fun to knead, stretch, mold, and shape. Adding glitter, dye, and scented oils allows crafters to customize the sensory stuff to their liking, but that's just the beginning: Other additives can make slime magnetic, glow-in-the-dark, heat-responsive, and more.

But there's more to slime than glitter and eye-popping colors; there's a surprising amount of science behind the stuff. For starters, the substance is a non-Newtonian fluid, a liquid that doesn't conform to "normal" models of viscosity, meaning that its viscosity is affected by not temperature but force or stress. Making slime is a fantastic way for kids to experiment with the way non-Newtonian fluids act.

Then there's the science of how the glue reacts with other ingredients. Glue is a type of polymer, made of long chains of polyvinyl acetate molecules, which slide around and allow the glue to be squeezed out of the bottle. Adding Borax—also known as sodium borate or sodium tetraborate—to the mix results in cross-linking between the glue's protein molecules and the borate ions. The reaction links large molecules together, creating even bigger molecules that prevents them from sliding as easily and creates the slime texture. [PDF]

Though most of the original recipes included Borax, which is primarily used as a cleaning agent, reports quickly surfaced of kids suffering from serious chemical burns after submerging their hands in the substance for too long.

To avoid any mishaps, we've rounded up three of the best basic slime recipes that don't require the use of Borax. Grab the Elmer's while it's still on the shelves, and put a couple of these slime recipes to the test.

CONTACT LENS SOLUTION SLIME

After conducting their own tests to determine a safe way to create slime, Elmer's came up with a concoction that uses contact lens solution.

First, mix together 4 ounces of Elmer's white school glue with a 1/2 tablespoon of baking powder and a 1/2 tablespoon of baking soda. Knead the slime until you get your desired viscosity, adding drops of contact lens solution until you're happy with the result. Add dye, glitter, or other additives as desired.

CORNSTARCH SLIME

For slime that's less ooey-gooey and more fluffy-puffy, try a combination of a 1/2 cup of shampoo and a 1/4 cup of cornstarch. Add 1 tablespoon of water and stir. Mix in 5 more tablespoons of water, one tablespoon at a time, stirring well after each addition. If your slime is too sticky, knead in more cornstarch until you get it to a dough-like consistency.

SHAVING CREAM SLIME

Using shaving cream will give this version an extra fluffy feel. Mix a tablespoon of baking soda with just enough contact lens solution to cover it. Mix until combined. In a separate bowl, fold together a 1/2 cup of glue with a 1/2 cup of shaving cream. If you want colorful slime, add food coloring before folding. Add the baking soda solution and mix until putty-like. Knead the slime for about three minutes, then place in a sealed container. It should be ready to play with in an hour or two. 

Brie Larson Punched an Old Woman in the Captain Marvel Trailer—This Might Explain Why

Marvel fans have been on cloud nine all day, a​s the first official trailer for the highly-anticipated film Captain Marvel was ​released this morning. Besides seeing Carol Danvers (a.k.a. Captain Marvel) in Air Force and her awesome suit, one quick shot certainly threw us off.

Toward the end of the trailer, ​Captain Marvel punches an innocent-looking elderly woman on a train, after the woman simply gave the superhero a smile. Upon first watch, we were so confused, and so were tons who took to social media to ask about it.

However, there is a pretty simple presumed explanation for Carol Danvers's action.

As Carol is back on Earth, she has to readjust to the planet she barely even remembers coming from. She's obviously rattled upon getting on the train, and when one person makes eye contact with her, she interprets it as danger. Comic book fans know Carol's dealt with Skrulls, which are shape-shifting aliens. We're assuming she thinks this poor old woman is one of them, and honestly, we can't blame her.

We don't have proof that this is what's going on, and Carol could technically just have some seriously bad anger issues we're not aware of, but we're pretty confident in this assumption, and so are tons of fans.

We'll find out what really happens when Captain Marvel hits theaters March 8, 2019.

Star Wars geekery has been taken to the next level. Underwear brand MeUndies just unveiled a new pattern that bears the likenesses of several of the space opera's most iconic characters and glows like a lightsaber when it gets dark outside.

The original pattern was hand-drawn by the MeUndies team, and it features Chewbacca, Yoda, R2-D2, C-3PO, Darth Vader, and a Stormtrooper. According to the company, it’s the first time a Star Wars print has featured characters from both the Dark Side and the Rebel Alliance together.

And naturally, the stars and Star Wars logos glow in the dark. The underwear is made from a fiber called Lenzing MicroModal, which is derived from beechwood trees and is said to be three times softer than cotton.
