Study Notes
Slime Properties
- Slime is made of polymers, long chains of large molecules called monomers
- When monomers link together, they create slime's bouncy stretchiness
- Slime can act like a liquid or a solid, due to high viscosity (thickness) - 20,000 times thicker than water
Slime in Space
- In May 2020, NASA astronauts tested slime on the International Space Station (ISS)
- Slime floated in a perfect sphere in microgravity
- When spun, the slime stretched into an oblong shape
Slime Uses in Nature
- Snails and slugs use slime trails to communicate and find mates
- Parrotsfish use mucus bubbles to safely sleep
- Velvet worms use slime to trap prey
- Hagfish use slime to deter predators, which hardens in seawater
- Aquatic limpets use slime trails to return home
Basic Ingredients
- Common homemade slime recipes combine glue, baking soda, contact lens solution, and water
Slime Facts
- The heaviest slime ever made weighed over 10,000kg (roughly the same as a garbage truck)
- The most popular spot for slime lessons was at the Montreal Science Centre in June 2022
Human Mucus
- Humans create a natural slime called mucus
- Mucus in the mouth and throat helps keep things moving smoothly
- Mucus in the lungs keeps them moist
- Mucus protects the eyes from dirt, dust and pollen
- Mucus in the nose and sinuses stops pollen, dust and bacteria from getting in
- Mucus in the intestines helps food move along smoothly
- Mucus in the stomach protects it from acid
