Elastic Hair Tie

This picture was taken in San Jacinto residence hall. It is of an elastic hair tie that uses potential energy to hold the hair in place, and out of my face.

Slinky, Spring

This slinky, when fully outstretched has Elastic potential energy. When I let go, the slinky contracts, changing that potential energy into kinetic energy.

Contigo Water Bottle (Elastic)

The elastic mouth piece is connected to the underneath of the cap, all as one piece, where it holds the straw in place (the left picture shows the tube connecting the mouth piece and the straw holder). As you bend the mouth piece into a "closed" position (right picture), potential energy is stored in the elastic, as the tube is bent. When you push the button underneath the mouth piece, it pushes the white component (as seen in picture on left), releasing it from the gray catch connected to the mouth piece, and releasing kinetic energy as the mouth piece pops out into "ready-to-drink" position.

These stretchy pants are great for days that you don't care what you look like!

Hair Band by Colin Blackmon

A hair band. It's use is to obviously hold hair by constraining it. Pretty simple idea, but ideal for weird pony-tail guys.
