Study Notes
Slime Properties
- Slime is made of polymers, long chains of large molecules called monomers
- Slime has an amazing bouncy stretchiness
- Slime can act like both a liquid and a solid
- Slime has a high viscosity (thickness) – up to 20,000 times thicker than water
Slime Ingredients
- Homemade slime can be made using different combinations of ingredients
- A common recipe involves glue, baking soda, contact lens solution, and water
Slime in Space
- In May 2020, NASA astronauts brought slime to the International Space Station (ISS)
- Slime behaved in microgravity, floating in a perfect sphere and stretching into an oblong shape when spun
Mighty Mucus
- Humans produce a natural slime called mucus
- Mucus protects eyes by preventing dust, pollen, etc. from entering
- Mucus keeps the lining of the mouth and throat moist, allowing things to move smoothly
- Mucus lines the lungs to help them function properly
- Mucus in the intestines helps food particles pass easily through
- Mucus in the stomach protects its lining from the acidic environment
- Mucus can trap bacteria and other invaders
Animals and Slime
- Snails and slugs use slime trails to communicate and find mates
- Parrotfish use mucus bubbles for protection and sleep
- Velvet worms use slime to capture prey
- Hagfish use a protein, mucin, which turns into a thick slime to deter predators
- Aquatic limpets use slime trails to find their way back home
Slime Facts and Figures
- The world's largest slime weighed 10,350 kg (22,817 lb).
- The largest slime was made in June 2018, in Austria
- 491 people learned about slime at the Montreal Science Centre in June 2022
