Science Bit
If you try to hit this slime, it will act like a solid and you’ll get sore knuckles. If you gently poke your finger inside the mixture, it will feel like a liquid. Strange, huh? Hundreds of years ago famous scientist Sir Isaac Newton wrote about how liquids behave. Slime like this is known as a Non-Newtonian fluid because it doesn’t play by his rules!
