Push Pin
Transcript: Technology of the Push Pin The push pin is related to science by they way the scientists figure out what material to make the push pin out of and how to get the push pins to stay in the wall. How The Push Pin is Used Today -The push pin shouldn't be used for heavier items such as heavy pictures or photos with glass *The picture may slip and fall The push pin is a thumbtack with a spherical head of colored plastic, used to fasten papers to a bulletin board or to indicate positions on charts and maps. How the Push Pin Was Originally Used Different types of Push Pins What is the Push Pin? Today, the push pin is used as a tack for attaching papers to a bulletin board or drawing board. There are many different types of push pins. Some are thumbtacks, wall clips, drawing pins and map push pins. They all have the same use and help in the same way, but may look different. The technology behind the push pin is how to keep the pin in the wall. http://invent.answers.com/clothing/the-invention-of-the-push-pin-and-its-usages-today http://www.wisegeek.com/what-is-a-push-pin.htm http://inventors.about.com/od/pstartinventions/a/Push_Pin.htm http://en.wikipedia.org/wiki/Push_pin http://www.push-pin.com/history http://www.google.it/patents/US1120656 Push Pin Disadvantages The push pin was orginally used as a pin used to fasten items to a wall or board for display and to be inserted by hand, generally without the assistance of tools. The push pin, also known as a thumbtack or drawing pin, was created by Edwin Moore in 1900. Moore founded a new company, called the Moore Push Pin Company, with only $112.60. Later, in 1904, German clockmaker Johann Kirsten invented flat-headed thumb tacks for use with drawings. The mathematics of the push pin is determining its size and shape. Katie Lynch The plastic "handle" of the push pin not only makes the pins easy to push into a bulletin board or wall, but aslo easy to remove. The push pin is ideal for hanging light weight items on walls and for pinning items to a surface.
