- 05
Humans produce about 1.5 liters of saliva daily. Saliva aids in digestion and keeps the mouth moist.
Animal Functions
Animals have unique ways of functioning that help them survive in their environments.
- 06
A cheetah can accelerate from 0 to 60 mph in just a few seconds. This makes it the fastest land animal.
- 07
Dolphins sleep with one eye open. They shut down one hemisphere of their brain to rest while the other remains alert.
- 08
A hummingbird's heart can beat up to 1,260 times per minute. This rapid heartbeat supports their high-energy lifestyle.
- 09
Octopuses have three hearts. Two pump blood to the gills, while the third pumps it to the rest of the body.
- 10
A group of flamingos is called a "flamboyance." Their pink color comes from the carotenoid pigments in their diet.
Plant Functions
Plants have fascinating ways of functioning that allow them to thrive in various environments.
- 11
Plants convert sunlight into energy through photosynthesis. This process produces oxygen as a byproduct.
- 12
Some plants can "hear" water. Roots of certain plants grow towards the sound of running water.
- 13
Venus flytraps can count. They snap shut only after two trigger hairs are touched within 20 seconds.
- 14
Bamboo can grow up to 35 inches in a single day. This makes it one of the fastest-growing plants on Earth.
- 15
The world's oldest tree is over 5,000 years old. Known as Methuselah, this bristlecone pine is located in California.
Technological Functions
Technology has revolutionized how we live and work. Here are some facts about how various technologies function.
- 16
The first computer virus was created in 1983. Named "Elk Cloner," it was written by a 15-year-old student.
- 17
Wi-Fi stands for "Wireless Fidelity." It allows devices to connect to the internet without physical cables.
- 18
The first 1GB hard drive was released in 1980. It weighed over 500 pounds and cost $40,000.
- 19
Bluetooth technology is named after a Viking king. King Harald "Bluetooth" united Denmark and Norway in the 10th century.
- 20

Nature is full of wonders. Here are some facts about how natural phenomena function.
- 21
Lightning can heat the air to around 30,000 Kelvin. That's five times hotter than the surface of the sun.
- 22
A single bolt of lightning contains enough energy to toast 100,000 slices of bread. This immense power is released in a fraction of a second.
- 23
Tornadoes can have wind speeds over 300 mph. These powerful storms can cause massive destruction.
- 24
The Earth's core is as hot as the sun's surface. Temperatures can reach up to 9,932 degrees Fahrenheit.
- 25
Auroras are caused by solar wind particles colliding with Earth's atmosphere. These collisions create stunning light displays.
Everyday Object Functions
Everyday objects have interesting ways of functioning that we often take for granted.
- 26
A ballpoint pen can write a line about 2 miles long. The ink is designed to flow smoothly and last a long time.
- 27
A single pencil can draw a line 35 miles long. It can also write around 45,000 words.
- 28
The microwave oven was invented by accident. Percy Spencer discovered it when a radar magnetron melted a chocolate bar in his pocket.
- 29
Velcro was inspired by burrs sticking to a dog's fur. Swiss engineer George de Mestral invented it in 1941.
- 30
Bubble wrap was originally intended as wallpaper. Inventors Alfred Fielding and Marc Chavannes created it in 1957.
Space Functions
Space is a vast and mysterious place. Here are some facts about how things function in space.
- 31
A day on Venus is longer than a year on Venus. It takes 243 Earth days to rotate once but only 225 Earth days to orbit the sun.
- 32
Neutron stars can spin 600 times per second. These incredibly dense stars are remnants of supernova explosions.
- 33
The International Space Station orbits Earth every 90 minutes. Astronauts experience 16 sunrises and sunsets each day.
- 34
Space is completely silent. Sound waves need a medium to travel, and space is a vacuum.
- 35
A teaspoon of neutron star material weighs about 6 billion tons. This extreme density is due to the collapse of a massive star.
