Understanding Slime Chemistry

Which molecule is the main component of Elmer's glue used in slime making?

• Sodium chloride

• Carbon dioxide

• Polyvinyl acetate (PVA)

• Water (H2O)

What is the role of borate ions in the slime-making process?

• They provide color to the slime.

• They cross-link with PVA molecules to form a new material.

• They dissolve the glue.

• They evaporate to harden the slime.

What is the first step in making slime according to the video?

• Adding borax directly to glue

• Mixing glue with water

• Adding food coloring to water

• Heating the glue

Why is slime considered a non-Newtonian fluid?

• It can only be stretched, not torn.

• It changes color when stretched.

• It has both liquid and solid properties.

• It is made from natural ingredients.

What happens to the borate ions when stronger forces are applied to the slime?

• They temporarily disconnect and then reconnect with the polymer chains.

• They permanently break away from the polymer chains.

• They evaporate into the air.

• They change color.
