Why are liquids slippery?

Kayla 

Liquids are slippery because the particles making up liquids are able to slide over each other.

Kayla, I have more information for you about liquids being slippery. Liquids: Particle Movement

Sticky substances have an attraction for other substances. Water is a bit sticky--molecules of water stick together. Dip your thumb and index finger in water, and then press your wet finger against your wet thumb. Slowly separate your fingers to see how far a string of water between them can be stretched. Like molecules attract each other because of a force called cohesion. Repeat the experiment replacing the water with maple syrup.

The part of perfume that gives it a specific smell is called its  “juice.” Juice is a mixture of different oils, each with a specific scent. You smell these scents because they evaporate, which means to change from a liquid to a gas. These scented gas molecules move through the air and you smell them when they enter your nose. The more scent molecules that enters your nose, the stronger is the smell.

Here is what happens when perfume molecules enter your nose:

1. Special cells on the inside surface of your nose capture the molecules.

2. These special “smelling cells” have hairlike bristles covered with a slippery substance called mucus.

3. The perfume molecules dissolve in the mucus.

4. The bristles send a coded message to your brain.

5. Your brain decodes the message and identifies the smell.
