Have you ever played with Tinker Toys or Lincoln Logs? Do you have a Raggedy Ann doll? Just think about the toys that your great-grandparents, grandparents, or your parents may have played with when they were your age. Here are just a few of the popular toys in history that may still be around today. Check out from what, how, and when these toys were invented and the chemistry that was involved in discovering or creating each of them. Kites:-What is it? A light-weight frame covered with material that can be flown in the wind. History: People in China discovered kites. Because they were invented so long ago, no one knows exactly by whom or how they were developed. Where’s the Chemistry? Chemists have used kites to collect air in the atmosphere. They can study the air to measure certain types of chemicals, like carbon dioxide and oxygen. Interesting fact: Kites have been used in many different ways: to fish, to help build a bridge and to deliver messages Crayons:-What is it? A small stick of wax that comes in different colors made for drawing. History: Edwin Binney and C. Harold Smith saw a need for a more affordable and better quality crayon. Where’s the Chemistry? Crayons are made from two types of materials. The first is called a wax. Wax can be a solid or a liquid that comes from petroleum, a natural material found deep in the earth. The second material is a pigment. It is a substance used to give color. Interesting fact: The first known crayons were made in Europe from recipes used by the ancient Greeks and Romans.
Balloons:-What is it? A flexible bag normallyfilled with air or other gas. Neil Tillotson drewa picture of a cat’s head on card board, cut it out, and dipped it into sap from a rubber tree. When it dried, he peeled it off and blew it into a “cat balloon”. Where’s the Chemistry? Latex is a naturally occurring milky sap that comes from rubber trees. Latex balloons can be filled with helium, air, or water. Interesting fact: Latex balloons are biodegradable. Biodegradable means the balloons will begin to break down like leaves in our backyard Clay:-What is it? A non-toxic moldable plastic modeling clay. History: Young Joe McVicker invented this putty-like substance to clean the smudges off of wallpaper. Where’s the Chemistry? The putty-like substance is a type of polymer that can be molded into different shapes. Interesting facts: Vanilla gives Play-Doh its special scent. At first it was available only in a 11⁄2 pound can in an off white color Ball:-What is it? A ball that bounces with six times the bounce of regular rubber balls. History: Norman Stingley was a chemical engineer who accidentally discovered the rubbery product, which he called Zectron. Where’s the Chemistry? Rubber is a type of polymer used in many toys. The ingredient that increases the Super Ball’s bounce is a secret to this day. Interesting fact: The name of the NFL championship game “Super Bowl”, was inspired by the toy’s name, super ball
