The color of the first bubble gum was pink simple because it was the only color the inventor, Walter Diemer, had left.
Humans are the only creatures that can chew gum.
You can get a monkey to chew it for a few minutes, but then they'll just take it out and stick it in their hair. During the 1920's, Americans bought 700 million pounds of chewing gum a year. Chewing starts the saliva glands, so they make 250 percent more saliva. All that spit makes you swallow more, which opens the tube that goes from your middle ear to the back of your throat. This balances the pressure between your middle ear and the air outside your head, helping you adjust to the air pressure in the plane.
