The Tears Of A Clown
During a lesson on "Work", I decided to demonstrate how a force performed during displacement changes something's state of energy.
I placed a thermal camera in front of my computer and recorded our work as we transformed or chemical energy into thermal and kinetic energies while we danced; however, while trying to get my final class to dance, I jumped onto a table to give it all I had. I then began to dance. (Footage of style available on right)

Proof-of-concept video recorded with "Study Hall Crew" (Isabelle Sanchez, Tim Colon, and Ciarin Lamb) during prep. ***Note that the outline of bodies becomes very blurred as the atmosphere removes thermal byproduct from exercise.
Not actual footage of event with pants issue
A moment later, I noticed that the students were laughing more than they were dancing.
To my horror, I looked down to notice that I had split my pants.
I quickly got down and laughed with my students about it, but I was embarrassed. Luckily all the students were kind, but my lesson had failed, and I had torn a pair of pants to one of my favorite suits.
Tear length = 13cm (About five inches)
While at home, I was ruminating about the event when it dawned on me that my "pants malfunction" was a fantastic demonstration of the very idea that I was trying to show them.

I thought to myself, "The purpose of the stitch is to always create an equilibrium to any pulling force. The tension (force) of each crossing stitch can be measured in Newtons. The value of the force that pulls against them will be evenly divided across each stitch. If I apply 500N across 5 stitches, then each stitch will need to be able to support 100N of pull.
If one stitch fails, the forces will become unbalanced and the material will move and rare feeling of embarrassment will arise.
I am concerned there will not be a material strong enough to withstand these dancing legs. I am going to need a lot of stitches per unit area."
