In the spirit of the tradition established last year, we dedicated to the last lecture of PHY 131, Fall 2000, to "the most outrageous demonstration experiments".  We pulled ropes hanging from weights, fired Coke bottles across the room, bounced a tennis ball off a basketball, and Phil crushed a concrete block on Laszlo' stomach (again).  Tried to use the fire extinguisher as a propulsion tool (but it did not have enough charge), had the spinning bicycle wheel hanging from the ceiling, and made flames dance to music.  At the end we had balloons frozen in liquid nitrogen, and a demonstration that involved dry ice (solid carbon dioxide).  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.
