Description: This fun 5-min video is a rap/parody of a Smashmouth song that musically explains aerodynamics and airplane flight. There is a short explanation on the board, but for the rest, you have to listen to the lyrics!
Description: This 5-min video is a great explanation of how to make slime and why slime behaves the way it does. The video discusses non-Newtonian fluids, shear-thickening, monomers and polymers, all in a very easy-to-understand format.
Description: A wheel is rotated suspended from a rope. It is (almost perfectly) tuned as a variant of a Wilberfoce pendulum, coupled oscillator.
It changes from upright circular motion with no pendulum swing, to a flat circular motion with a large swing and back.
I think that it's precession becomes pendulum motion, and the wheel goes flat. Because of the swing, the flat circle feels a gyroscopic force and rises once again to the upright position at the expense of the pendulum motion.
Please figure out the normal modes and the equations of motion for this system. I've never seen it discussed in the literature.
Description: This GOOFY 5-min video is heavy on the silliness and light on the science. The 'actors' go back in time to see a dinosaur and get a quick explanation of fossilization from a time-traveling wagon.

Jason Lindsey aka “Mr. Science” with Hooked on Science and a kid scientist show us why you should never get a Styrofoam cup close to acetone.
