Why is blue for boys and pink for girls?

In ancient times, it was believed that certain colors could combat the evil spirits that lingered over nurseries. Because blue was associated with the heavenly spirits, boys were clothed in that colour, boys then being considered the most valuable resource to parents. Although baby girls did not have a color associated with them, they were mostly clothed in black. It was only in the Middle Ages when pink became associated with baby girls.

If blood is red, why are veins blue?

Blood is bright red in its oxygenated form and a dark red in deoxygenated form. In simpler terms, it is bright red when it leaves the lungs full of oxygen and dark red when it returns to the lungs for a refill. Veins appear blue because light penetrating the skin is absorbed and reflected in high energy wavelengths back to the eye. Higher energy wavelengths are blue.

Why does wet fabric appear darker?

When fabric gets wet, light coming towards it refracts within the water, dispersing the light. In addition, the surface of the water causes incoherent light scattering. The combination of these two effects causes less light to reflect to your eyes and makes the wet fabric appear darker.

Why are camels called “ships of the desert?”

Camels are called “ships of the desert” because of the way they move, not because of their transport capabilities. Camels sway from side to side because they move both legs on one side at the same time, elevating that side. This is called pacing, a ship-like motion which can make the rider feel sick.

Why does water not calm the tongue after eating hot spicy food?

The spices in most of the hot foods that we eat are oily, and, like your elementary school science teacher taught you, oil and water don’t mix. In this case, the water just rolls over the oily spices.

What can you do to calm your aching tongue? Eat bread.The bread will absorb the oily spices. A second solution is to drink milk. Milk contains a substance called “casein” which will bind to the spices and carry them away. Alcohol also dissolves oily spices.

Why are there bunnies and eggs at Easter?

The ancient Anglo-Saxons celebrated the return of spring with a carnival commemorating their goddess of offspring and of springtime, Eostre. The word carnival possibly originated from the Latin ‘carne vale’ meaning “flesh, farewell” or “meat, farewell.” The offerings were rabbits and coloured eggs, bidding an end to winter.

As it happened, the pagan festival of Eostre occurred at the same time of year as the Christian observance of the Resurrection of Christ and it didn’t take the Christian missionaries long to convert the Anglo-Saxons when they encountered them in the second century. The offering of rabbits and eggs eventually became the Easter bunny and Easter eggs.
