🤔 How it works …….. ⁉
How a crayon is made
A crayon (or wax pastel) is a stick of pigmented wax used for writing or drawing. Wax crayons differ from pastels, in which the pigment is mixed with a dry binder such as gum arabic, and from oil pastels, where the binder is a mixture of wax and oil.
The two basic ingredients for a crayon are:
1. Pigment
2. Paraffin wax, stored in heated 17,000 gallon tanks
The mixture is heated until it melts into a liquid. Crayons melt at 105 degrees Fahrenheit (40 degrees Celsius). The mixture is heated to 190 F (82 C). The liquid is poured into a preheated mold full of hundreds of crayon-shaped holes. Cool water (55 F, 13 C) is used to cool the mold, allowing the crayon to be made in 3 to 9 minutes.
A single mold makes 1,200 crayons at a time, weighing a total of about 40 pounds. The operator uses hydraulic pressure to eject the crayons from the mold. Earlier mold designs used a hand crank to push up the crayons.
😳Why❓❓❓
Why we get dreams while sleeping?
Dreams are hallucinations that occur during certain stages of sleep. They’re strongest during REM sleep, or the rapid eye movement stage, when you may be less likely to recall your dream. Much is known about the role of sleep in regulating our metabolism, blood pressure, brain function, and other aspects of health. A dream is a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep.
Adults and babies alike dream for around two hours per night. During a typical lifetime, people spend an average of six years dreaming. The average person has three to five dreams per night, and some may have up to seven.
People who are blind from birth do not have visual dreams. Their dream contents are related to other senses like hearing, touch, smell and taste, whichever are present since birth
