PHY 131 Demo experiments, Fall, 1999

These photos were taken on the last lecture of PHY 131, Fall 1999, entitled "The most outrageous demonstration experiments".  We started out with the conservation of energy and momentum, and a concrete block was crushed on Laszlo' stomach.  We covered Newton's third law (rocket made of a coke bottle), resonance in closed-end tube (dancing flames and music), inertia (spinning eggs), torque and angular momentum (spinning a bycicle wheel) and we had lots of fun. Thanks for the Instructional Lab (Joe and Frank) for enduring our persistent requests and helping us to put up the show.
