Who Knew? Facts You Probably Didn’t Know What would bounce higher, a glass ball or a rubber one? Did you know that a ball made of glass will bounce higher than a ball made of rubber? Seems impossible, but it’s true! When a rubber ball hits a surface, it deforms a little. This makes it lose energy. Unlike the rubber ball, a glass ball does not squish against the surface before jumping up. This retains energy for it to bounce higher. A way to test how well it will bounce back up is to test how it rings. When you strike a marble, you can hear a ringing sound, same for a bell, or a bouncy ball. For example, if one bell is made of rubber and another is made of glass, which one do you think will ring louder? The glass one will definitely ring louder, also meaning that it will bouncer higher. If you compare the sound of a glass bell to a steel bell, you will find that the steel bell has more sound. A steel ball will bounce higher than a ball made of glass. You can test it for yourself, get a rubber ball, a glass ball, and a steel ball. Drop from a height of a few centimeters on a hard surface. You will find that the glass ball will bounce higher than the rubber ball, and the steel ball will bounce higher than the glass ball.

Did you know that after learning new information, taking a nap can help your retain the new information you learned?Many studies prove this fact. A study of preschoolers that took a nap after learning new verbs proved that they knew them better after 24 hours compared to preschoolers that didn’t take nap.According a harvard study in 2010, volunteers were taught how to navigate a maze. During a break, select few were allowed to take a 90 minute nap. Those who were allowed to sleep, did overall better than those who did not. A german study proved that a nap of six minutes helped volunteers memorize a list of 30 words. Different length naps help you with different things, although all naps allow for information to be processed. Sources 8

Did you know that the color magenta is not visible in the color spectrum? Magenta does not have wavelength of light. Then why are we able to see magenta? Magenta is the complementary color to green. Every color has a complementary color. When we stare at a green light for a long period of time then look away we will see magenta.
