How fast is a lightning bolt?
Its can depend on air conditions, but the typical lightning bolt moves at 224,000 mph -- or about 3,700 miles per second. However, the light you see from the lightning obviously travels at the speed of light, which is roughly 670 million mph, or 186,000 miles per second.

What is the temperature of dry ice?
Dry ice is frozen carbon dioxide. A block of dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5 degrees C). Dry ice also has the very nice feature of sublimation -- as it breaks down, it turns directly into carbon dioxide gas rather than a liquid.

Are crayfish and crawfish the same thing?
Crayfish, also known as crawfish, crawdads, freshwater lobsters, or mudbugs, are freshwater crustaceans resembling small lobsters, to which they are related; taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea.

What colors make you feel hungry?
It's one of the reasons why most fast food colors are orange and red and why the color yellow makes babies cry. We know through many scientific tests that red causes us to feel hungry and we know that yellow makes babies think they are in the sunlight so thy cry to tell their moms that they don't like it.

Do whales have a nose?
They have nostrils called blowholes. Over millions of years of evoloution whales and dolphins nostrils moved to the top of their head. This allows them to breath by surfacing instead of them sticking their whole head out of the water. The first thing a newborn dolphin must do is to go to the surface to breathe.

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.
