14. The rarest blood type is AB-. This blood type is found in less than 1% of the world's population. These folks can donate plasma that is compatible with any other blood type.

15. The scientific study of algae is called phycology. Also known as algology, it involves studying seaweed ecosystems.

Physics Fun Facts

1. There are four states of matter in the universe: solid, liquid, gas, and plasma, each with distinct properties.

2. Electron pairs create covalent bonds when shared between two atoms, essential for forming molecules.

3. Geiger Counters measure radiation, detecting ionizing particles through electrical pulses.

4. Newton's third law of motion states that 'for every action, there is an equal and opposite reaction.’ This principle is fundamental in understanding forces and interactions.

5. Sound travels faster in water than in air. In fact, it moves about four times faster in water.

6. Lasers work by focusing light waves, not sound waves. "Laser" stands for Light Amplification by Stimulated Emission of Radiation.

7. A Van de Graaff generator is a scientific tool used to teach about static electricity. It uses a moving belt to accumulate an electric charge.

8. Friction is the force that occurs when solid surfaces rub against each other. Objects have different amounts of friction depending on how rough or smooth they are.

9. Cones in the human eye allow us to see wavelengths of light. There are three different types of cones, each corresponding to a different color wavelength.

10. Radiation is the transfer of waves or particles from one place to another. Examples include light, sound, heat, and X-rays.

11. Endothermic reactions absorb heat from their surroundings and make things colder. Examples include melting ice cubes and cooking an egg. What? Want more egg facts? We got um.

12. Planes stay in the air due to the shape of their wings, which force air downward and create lift. This lift counteracts gravity, allowing planes to fly.

13. Electrons are smaller than atoms. Atoms are composed of protons, neutrons, and electrons, making electrons the tiniest component.

14. Diamonds do not last forever; they eventually degrade to graphite over billions of years. Graphite is what pencil leads are made from.

15. An insulator is a material that will not carry an electrical charge. Examples include rubber, glass, and plastic.

16. Hot water freezes faster than cold water due to the Mpemba effect. It's a paradoxical phenomenon that's still not fully understood.
