Step into a loop band or tie a therapy band around your lower legs just above your ankles.

The rubber band has lower entropy is more ordered when stretched.
Suppose the system is the rubber band and the air in a large room.
Place feet shoulder width apart to create tension on the band.
However rubber deviates from elastic behavior in two ways.
Thus the entropy of the rubber band increases when it goes from the stretched state to the natural state.
Shoot at least five rubber bands for each stretch length.
Start in a half squat position.

After each launch have your helper.
Shoot more rubber bands in the same way except stretch them back to 15 cm 20 cm 25 cm or 30 cm.
First rubber bands only slowly return to their original state after being released leading to hys teresis in tension measurements a different tension is meas ured when a rubber band is stretched to a given.
The y variable is the amount of pressure necessary to stretch the band.
I suppose your best bet would be to take a sample of some large.
The x variable is the number of inches the band is stretched to.
