Summer holidays are almost over and it’s time to head back to the wonderful world of learning. To make your learning journey interesting, we have a fun activity where you can create, play and learn a thing or two about science.

Welcome to the world of SLIME!

Have you wondered what this slimy, gooey substance is all about?

For beginners, this sticky, stretchy, ooey-gooey substance is one of the most popular sensory play experiences. Mattel, a toy company, first created the slime in 1976. A glossy green slime designed by them was sold in a tiny plastic bottle called ‘trash can’. Today, making slime has become one of the favourite pastime activities for children mostly because it’s engaging and has a scientific connection.

So, what’s the science behind the slime?

According to Sir Isaac Newton, fluids like water or honey have a constant viscosity (flow). These fluids change their flow behaviour only when there’s a change in the temperature or pressure. Water, for example, freezes and turns into solid (ice) when the temperature is reduced to 0 degrees celsius and when the temperature is increased to 100 degree celsius, water changes to gas. This is known as Newton’s Law of Viscosity. The fluids that obey this law are Newtonian fluids.

But there are certain fluids which do not follow the law. In fact, they go against the law and change their viscosity or flow behaviour under stress. Such fluids are Non-Newtonian fluids. Slime is one such Non-Newtonian fluid that behaves like a solid and liquid depending on the stress (like knead or shake them) applied. Interesting, isn’t it?

Now, that we know the science behind the slime, let’s explore some awesome Do It Yourself (DIY) slime recipes you can make at home.

BYJU’S SLIME RECIPES

#1 Experiment: Unicorn Fluffy Slime

Instructions

  1. In a large bowl, mix the glue and shaving cream with an ice cream stick.
  2. In another bowl, mix 1/2 teaspoon of borax powder with one cup of water. Stir until the borax powder is dissolved completely.
  3. Add about a teaspoon of that mixture into the glue and shaving cream bowl and stir.
  4. Knead the mixture well. If it’s too sticky, add a little borax and water mixture.
  5. Once your fluffy slime recipe is ready, separate it into three pieces.
  6. Now add a drop of pink food colouring to the first piece of slime and knead until the entire piece turns pink.
  7. Repeat with the other two pieces of slime by adding one drop of blue and one drop of yellow to them.
  8. When all the three pieces are coloured, mix them together.
  9. The longer you knead the slime, the better is the blend of colours.

Tip: You can also add glitter to your slime while kneading to give it a sparkly touch!

#2 Experiment: Liquid Starch Slime

Instructions

  1. In a large bowl, add glue and 1/2 cup of water and mix well.
  2. Squirt in a few drops of paint to the bowl and mix well. You can also divide the slime into 2-3 mini bowls and add different colours to it.
  3. Slowly add liquid starch a little at a time, constantly stirring to make sure it’s mixed well. You’ll be able to tell when it comes together.
  4. Knead the slime as the consistency thickens.

#3 Experiment: Foam Ball Slime

Instructions:

  1. Pour 1/2 cup of glue into a bowl and add food colour of your choice. Stir this mixture well with a popsicle stick.
  2. Now add 1/2 cup of liquid starch into the mixture and squish the mixture with your hands. If it’s sticky, add more starch.
  3. Add polystyrene balls into the mixture and mix them well with your hands.
    Safety measures first!

  • Make sure you wear rubber gloves and goggles before you begin your experiments.
  • Read and follow the cautions on the borax box label.
  • If you are too young, take help from your elders while mixing borax with glue or water.
  • Once your slime is ready, store it in an airtight container.

  We hope you had fun making slime 🙂 Share your unique homemade slime recipes with us!
