Making Slime

The video tutorial explains the concept of non-Newtonian liquids, which can behave like both a liquid and a solid without a change in temperature. It demonstrates how to create a non-Newtonian liquid using PVA glue, Borax, and food coloring. The tutorial describes the unique properties of the slime, which behaves like a solid when stress is applied and like a liquid when left undisturbed. The scientific explanation involves polymer chains in the glue that become cross-linked with Borax, allowing the slime to change states based on applied forces.

What is a non-Newtonian liquid?

• A liquid that changes state with temperature

• A liquid that behaves like a solid under stress

• A liquid that is always solid

• A liquid that evaporates quickly

Which materials are used to create the non-Newtonian slime in the video?

• Water, salt, and sugar

• Vinegar, baking soda, and oil

• Sand, water, and clay

• PVA glue, Borax, and food coloring

What happens to the slime when it is left on a flat surface?

• It evaporates

• It changes color

• It spreads out like a thick liquid

• It hardens into a solid

How do the polymer chains in PVA glue behave when mixed with Borax?

• They break apart

• They evaporate

• They become cross-linked but can still flow

• They dissolve completely

What causes the slime to behave like a solid when bounced?

• The slime dries out

• The temperature increases

• The polymers dissolve

• Friction locks the polymers together

What happens to the polymers in the slime when no force is applied?

• They become solid

• They evaporate

• They move past each other

• They lock together

What is unique about the slime created in the video?

• It evaporates quickly

• It is always a solid

• It can behave like both a solid and a liquid at the same temperature

• It changes color with temperature
