How To Activate Slime : Instructions To Make Slime
When you pick it up, it oozes between your fingers, but it doesn’t adhere to your skin. As a liquid at times, it appears to be a solid at others. Inquiring minds want to know what it is. This is, of course, SLIME. All I can say is “slime!” Many budding scientists enjoy making slime as a pastime.
In the end, the result is always a cool concoction that provides hours of fun, acts as a great stress reliever, and serves as a platform for learning many important scientific principles. So, to learn more about this gooey fluid, here’s a kit you can put your hands on! Borax is used in our household! Borax (disodium tetraborate) and laundry detergent are both used in the slime activator.
As a naturally occurring compound, borax has been found to be non-toxic and poorly absorbed by the skin in low concentrations. Consider wearing eye protection and gloves to prevent contact with broken skin if you are going to be exposed for an extended period of time.
THE SCIENCE OF SLIME
The term “slime” refers to a fluid that is neither Newtonian nor viscous. Shear stress, a property of non-Newtonian fluids, describes the fluid’s ability to change viscosity in response to external forces. Squeezing, stirring, agitating, or applying mechanical pressure to the fluid’s surface are all examples of shear stresses.
A non-Newtonian substance’s viscosity can be significantly influenced by any of these factors. Corn flour dissolved in water is the most common example of a non-Newtonian fluid. This fluid’s properties resemble those of quicksand. When squeezed, it forms a solid ball; however, releasing the pressure causes it to revert to a liquid state.
Slugs and snails, for example, produce their own slime that allows them to travel over rough terrain and leave a scent trail to help them find their way back. During an attack, hagfishes can quickly and easily produce large amounts of slime as a defence mechanism. Polyvinyl acetate (PVA) glue and borax are used to create the slime in this experiment.
In order to construct PVA glue, polyvinyl alcohol molecules are linked together in long chains. The glue can be dispensed from the bottle with ease thanks to the chains’ ease of movement. However, the addition of borax to the glue results in a viscous and resilient slime. Cross-linking between the protein molecules of the glue and the borate ions of the borax solution causes this type of slime to form. Cross-linking is the process of forming bonds between large molecules, preventing them from sliding past one another. The result is a tangled mass known as slime, which we all enjoy.
How To Activate Slime
YOU WILL NEED
• 30ml PVA glue (white or clear)
• Paint or food coloring
• Glitter and sparkles
• Slime activator (shake well before use)
• 3ml Pipette
• Lolly stick
INSTRUCTIONS TO MAKE SLIME:
1. Taking the pot of PVA glue, mix in the paint or food coloring and sparkles.
2. Add approximately 2-4ml of the slime activator mixture, a few drops at a time, mixing it thoroughly.
3. Stir with the lolly stick until it becomes stiffer and comes away from the sides of the pot, leaving the pot clean and forming a ball around the stick. You may need to scrape the slime off the stick (on the side of the pot) as you mix it, to get the right consistency throughout.
4. Remove the slime and knead it to check consistency and add a drop more activator onto your hands if necessary.
**SAFETY WARNING** Not for consumption. Not suitable for children under 3 years.
MIX IT UP
• Try adding a teaspoon of corn flour to white PVA at the start to create bouncy putty.
• Try adding a teaspoon of hair conditioner to white PVA at the start to create silky slime.
• Try adding a teaspoon of shaving foam to a mix of white and clear PVA at the start to create fluffy slime.
WHAT IS A SLIME ACTIVATOR, AND HOW SHOULD IT BE USED?
In order to create and maintain the chemical reaction that produces slime, slime activators are required. Borax (disodium tetraborate) and laundry detergent are used to activate our slime. Eventually, the chemical reaction that produces slime weakens, resulting in a sticky, goopy substance. In order to get the desired slime texture, simply add small amounts of activator and knead it in. To ensure that your slime is the right consistency, only add a small amount of activator at a time.
• DO not eat slime!
• Avoid contact with eyes, mouth and nose. In case of contact wash thoroughly with water!
• Keep away from clothes, carpet, furniture, pets, and hair!
• Do not use if you have a wound, swelling or eczema on your hands or arms!
• Do not use if you show symptoms such as a rash or itchiness after playing with slime!
• Always wash your hands before and after handling slime!
