What color is a baby's eyes at birth?
Babies of African and Asian descent are usually born with brown eyes that stay brown. Caucasian babies are often born with steel gray or dark blue eyes; they may stay gray or blue or turn green, hazel, or brown by the time they're 9 months old.

What does a camel store inside its hump?
Camels do not store water in their humps, as it is commonly believed. The humps are actually reservoirs of fatty tissue. Concentrating body fat in their humps minimizes heat-trapping insulation throughout the rest of their body, which may be an adaptation to living in hot climates.

Can there be thunder and lightning without rain?
Dry thunderstorm refers to thunder and lightning that occur without bringing rain to the ground. In fact, the thunder-bearing clouds do produce rain but the rain droplets have evaporated in the air before reaching the ground.

Do dogs get cavities in their teeth?
Pets, like their human owners, can get cavities. However, cavities are relatively rare in dogs because dogs' diets generally are not high in decay-causing sugars. Veterinary dental experts have noticed a mild rise in the incidence of cavities among dogs fed sugary treats.

Why does an old bottle of aspirin smell like vinegar?
When aspirin ages, it gradually reacts with absorbed moisture from the air and partially reverts back to salicylic acid and acetic acid. In general, it's the above reaction run backwards. It is the acetic acid that smells like vinegar.

Is pure water a conductor?
Pure water is not a good conductor of electricity. Ordinary distilled water in equilibrium with carbon dioxide of the air has a conductivity of about 10 x 10-6 W-1*m-1 (20 dS/m). Because the electrical current is transported by the ions in solution, the conductivity increases as the concentration of ions increases.

Which is the only planet that rotates clockwise?
If you were to look down at the plane of the solar system from its 'north pole' you would see the planets orbiting the Sun counter clockwise, and rotating on their axis counterclockwise. Except for Venus. Venus would be rotating clockwise as it orbited the Sun counterclockwise.

What makes the sky blue?
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

Why are the nuclei of some atoms unstable?
In some atoms the binding energy is not strong enough to hold the nucleus together, and the nuclei of these atoms are said to be unstable. Unstable atoms will lose neutrons and protons as they attempt to become stable.

Why is it called a wisdom tooth?
Wisdom teeth are called wisdom teeth because they erupt (emerge) into the mouth when people are in their late teens or early twenties, affectionately termed the “Age of Wisdom.” Wisdom teeth are technically referred to as third molars, and they're just like all the other teeth in your mouth.

Can trees explode from freezing?
Cold weather will cause some trees to explode by freezing the sap, because it contains water, which expands as it freezes, creating a sound like a gunshot. The sound is produced as the tree bark splits, with the wood contracting as the sap expands.

What does the Mohs scale measure?
Mohs scale is used to measure the relative hardness of a mineral by its resistance to scratching. From softest to hardest, the ten minerals of the Mohs scale are talc (measuring 1 on the scale), gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and diamond (measuring 10 on the scale).

How hot does it get on Mars?
The temperature on Mars may reach a high of about 70 degrees Fahrenheit (20 degrees Celsius) at noon, at the equator in the summer, or a low of about -225 degrees Fahrenheit (-153 degrees Celsius) at the poles.

Do snakes have a good sense of smell?
Most snakes have an excellent sense of smell, in part to make up for their poor eyesight and limited hearing. Rather than a conventional nose, however, snakes sniff with an organ at the roof of the mouth called a Jacobson's organ, which is also found in a few lizard species.

How does a plant loses water?
Plants lose gallons of water every day through the process of transpiration, the evaporation of water from plants primarily through pores in their leaves. Up to 99% of the water absorbed by roots is lost via transpiration through plant leaves.

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.

Which animal sleeps about 20 hours a day?
The sleepiest animal in the world is the koala, who sleeps 22 hours a day. Next is the sloth (20 hours), armadillo and opossum (tied at 19 hours each), lemur (16 hours), then hamster and squirrel (tied at 14 hours each).
