The typical process consisted of combining polyvinyl alcohol solutions with borate ions in a separate mixing vessel. It feels cold and slimy to touch and also has an unpleasant odor.

Since then, slime saw its entry into school science laboratories and became a popular science project for children because it was very easy to make. Slime is an easy experiment to explain kids about chemical reactions, polymers and viscosity. Over the past few years, the internet has been buzzing with how-to videos on making slime with different materials and color combinations.

With slime becoming a major hype and trend amongst the youth, simultaneously, many risk factors of using slime surfaced. People were concerned about how safe slime was considering its chemical components. It triggered allergies in many children and some even found other health hazards.

Making Slime Using Borax

  • Ingredients
    White Glue
    Food Coloring

  • Tips:
    Instead of using white colored glue, you can also use a clear glue as it makes a translucent slime and adding a food color will give you the exact shade. After collecting the ingredients, you first head on to make the slime solutions. It consists of two components : first solution of borax and water and a second solution of glue, water and food coloring. You need to prepare the solutions separately.

  • Preparing the Slime Solution
    Begin by mixing 1 teaspoon of borax solution in 1 cup of water. Stir the solution until borax gets completely dissolved.

Important Facts on Slime

So now that you know how slime is made, here are some important facts on slime that are quite interesting.

How Does Slime Work?

Slime is a polymer made by the cross-linking of small molecules to form different flexible chains. The space between the chains is filled with water and the resulting substance has more structure than liquid water and yet less structure than solid. It can be called a stage between solid and liquid and wouldn’t be wrong to call slime a ‘confused’ element.

When borax is added to water, it forms a solution called borate ion. This solution, when added to the second glue solution, helps the ions to make bonds between the long polymer molecules with each other so that they cannot move and flow very easily.

Slimes are a non-Newtonian fluid, which means that their ability to flow or their viscosity is not constant. It changes according to different conditions. One such example of a kind of slime is Oobleck, which is a non-Newtonian slime. It flows like a thick liquid and yet stops flowing when it is punched or squeezed. The appearance of slime can be changed by changing the properties of glue and slime. You can play with the ratio between the two ingredients to get different types of slime. Adding more borax or more glue, might make the slime more stretchy or thick.

Is Borax Safe To Use in Slime?

There has been a lot of hype about the safety of slime owing to the presence of borax in it. Some people get skin allergies to different ingredients depending upon their skin sensitivity. Some people are allergic to borax and a slime made with borax might trigger allergies in them.

If slime is not eaten and not given to children who might put it in their mouth, then it is pretty safe to use. Consuming slime made from saline solution and borax can make people ill. Slime is generally non-toxic when made with borax. One should avoid eye contact, ingestion and prolonged skin contact from slime.

There are some other recipes to make slime without using borax too. You can use starch powder, baking soda, laundry detergents and contact lens solutions too, but their ingredients and recipes differ. You can try out other variations if you are particularly allergic to borax.

How to Store your Slime?

To store your slime, you need to keep it in a sealable plastic bag. It stays in best condition in a refrigerator or a in a cool place. There is no need to worry about insects swarming around your slime as borax is a natural pesticide. But chilling the slime in the refrigerator will prevent mold growth. The only problem with slime is drying as the water tends to evaporate. If sealed properly, slime does not get spoilt for a long time. Ensure that you don’t leave your colored slime on surfaces that can get stained by food coloring. Slime residue can be cleaned by soapy water.

Things to Do with Slime

Slime can be used as a stress toy because of its high level of flexibility. You can enjoy stretching it and watching it flow. The more you work on it, the stiffer it will get and eventually become like wall putty. It can be shaped and molded just like clay, but the only difference is that it will lose its shape soon.

The Best Substitute for Borax in Slime

Many people are skeptical about letting their kids coat their hands with borax powder. In that case, there are some good alternatives you can use:

  • A contact lens solution containing boric acid makes a good substitute for borax.

  • Cornstarch also makes an excellent substitute for slime.

  • Some people use powdered fiber containing active ingredient psyllium hydrophilic mucilloid, which gives the same result borax does.

  • Liquid starch used for getting wrinkles out of clothes, can also be used instead of borax.

  • Laundry detergent slime is another cheap option for making slime at home, although some detergents do contain borax but the quantity will be very less.
