Aer the powder is mixed with
the water, close the test tube
with the lid and shake it for
30 seconds. Let the contents
sit, shaking the tube every
few minutes, until they have
solidified. This takes about
15–20 minutes. Aer it has
solidified, you can open up the
test tube and have fun playing
with the slime.

The slime powder contains a material called a polymer.
Polymers are long molecules that are made up many
repeating parts, like a chain with many chain links. When
the polymer powder gets wet, the polymer molecules
aach together, growing longer. These long strands get all
tangled up with each other, like a bowl of spaghei. When
you stretch the slime, the tangled-up strands resist being
pulled apart. When you squish the slime in your hand, the
jumbled-up strands also resist being compressed too tightly
— like a handful of rubber bands!
