What connects the Pacific Ocean and the Atlantic Ocean?
The Panama Canal is not the only water line connecting the Atlantic and Pacific Oceans. There's a place in Wyoming—deep in the Teton Wilderness Area of the Bridger-Teton National Forest—in which a creek splits in two. Like the canal, this creek connects the two oceans dividing North America in two parts.

What percent of calories does the brain use?
While a brain takes up about twenty percent, or 300, of a resting body's 1300 calories a day, and while it has the potential to burn more, it's estimated that most actual thinking only changes the amount of calories that the brain burns by around twenty to fifty calories per day.

How long does it take for your body to digest a piece of gum?
You might have heard that swallowed gum stays in your stomach for 7 years.
That's not true.
Though your stomach can't break down a piece of gum the same way it breaks down other food, your digestive system can move it along through normal intestinal activity.

Why do lakes freeze from the top down rather than the bottom up?
The reason why ice forms on the top of lakes and ponds is that once water cools below 39 degrees Fahrenheit, it becomes lighter and less dense the more it cools. This means that water expands as it freezes into ice. As a result, ice takes up more room than the water it was made from.

Where are bees not found?
They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source and the latter primarily for protein and other nutrients.

When was the wireless phone invented?
A jazz musician named Teri Pall invented a version of the cordless phone in 1965 but could not market her invention, as its 2-mile (3.2 km) range caused its radio signals to interfere with aircraft communications. In 1968, she sold her rights to the cordless phone to a manufacturer who modified it for practical use.

What mineral is the hardest?
As it says in Mohs scale, the diamond is always at the most top of the scale, being the hardest mineral. There are ten minerals in Mohs scale, talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and for last and the hardest, diamond.

Do insects have lungs?
Instead of lungs, insects breathe with a network of tiny tubes called tracheae. Air enters the tubes through a row of holes along an insect's abdomen. The air then diffuses down the blind-ended tracheae. Since the biggest bugs have the longest tracheae, they should need the most oxygen to be able to breathe.

Can fish breathe out of water?
Though some fish can breathe on land taking oxygen from air, most of the fish, when taken out of water, suffocate and die.
This is because gill arches of fish collapse, when taken out of water, leaving the blood vessels no longer exposed to oxygen in air.

Why do airlines apply Speed Tape to their planes?
Airlines apply speed tape to their planes to temporarily repair minor damages to the aircraft's exterior.
Speed tape is a thin, aluminum tape with a pressure-sensitive adhesive. It is designed to withstand high temperatures and wind speeds, making it ideal for use on aircraft.
Speed tape is typically used to repair small dents, scratches, or cracks in the aircraft's skin. It can also be used to cover holes or gaps in the skin.
Speed tape is not a permanent repair, but it can keep the aircraft airworthy until a more permanent repair can be made.
The gaps between panels or fairings create drag if they aren't filled. The gaps also let water in, which can cause corrosion.
Normally, if they aren't removable panels that get opened all the time, they are sealed using a rubber compound called PRC to make a fillet seal.
The PRC takes a while to cure, so sometimes if a plane flies, the sealant will be covered with speed tape to stop it from getting damaged before it sets.
Or the seal will be temporarily made with just tape.
Or sometimes little fairings, bits of plane skin that are not structural, fall off or get damaged, and tape is used to replace them.

Which bird produces milk?
The pigeon is one of only three bird species (the others being flamingos and male emperor penguins) known to produce 'milk' to feed their young. In pigeons the milk starts to be produced in the crop of the parent birds two days before eggs hatch.

What does fire in the hole mean?
"Fire in the hole" is a warning that an explosive detonation in a confined space is imminent. It originated with miners, who needed to warn their fellows that a charge had been set.

Can a shark swim backwards?
Unlike fish, sharks cannot stop suddenly or swim backwards.
A shark's pectoral fins cannot bend upwards like a fish, limiting its swimming ability to forward motion. If a shark needs to move backwards, it uses gravity to fall, not swim backwards.

How long do dogs live on average?
Nearly 40% of small breed dogs live longer than 10 years, but only 13% of giant breed dogs live that long. The average 50-pound dog will live 10 to 12 years. But giant breeds such as great Danes or deerhounds are elderly at 6 to 8 years.

How long is a kangaroo baby when it is born?
The young kangaroo, or joey, is born alive at a very immature stage when it is only about 2 cm long and weighs less than a gram. Immediately after birth it crawls up the mother's body and enters the pouch. The baby attaches its mouth to one of four teats, which then enlarges to hold the young animal in place.

What percentage of the earth's water is drinkable?
Two percent of the water on earth is glacier ice at the North and South Poles. This ice is fresh water and could be melted; however, it is too far away from where people live to be usable. Less than 1% of all the water on earth is fresh water that we can actually use.

Why do flamingos stand on one leg?
Flamingos often stand on one leg, the other leg tucked beneath the body. The reason for this behaviour is not fully understood. Recent research indicates that standing on one leg may allow the birds to conserve more body heat, given that they spend a significant amount of time wading in cold water.
