- Al - I want to do something fun. Can I get access to an outdoor balcony of Nau Hall? I could then have the students gather on the ground below me and then I drop a series of different mass objects from great height showing the mass-independence of acceleration for objects in free fall near Earth's surface. Can you help identify a spot where we could do this? Chris ends up using 10-foot ITS-Classrooms ladder to do following: billiard ball v. baseball (same size, same shape, different mass), ...
bowling ball v. baseball (different size, same shape, different mass), ...
brick v. baseball (different size, different shape, different mass)

(I hanged the red 16-lb bowling ball on the "doubled up" 13ft yellow 120-lb braided fishing line. It worked "OK" but not that visible for the students. Next time, I'll also set up a pendulum in the front of the room so Chris has a prop to show while explaining the demo. - AL

- Hi Al - among these, the highest priority is standing waves. If it is easier to show a video for the glass-breaking, I can do that no problem. I may not get to dancing flames and chladni in this lecture but I will try. - Chris ... Post Lecture Update - We got thru all demos in the lecture live! - AL
- video - Standing Waves
(I suggest after doing the demo, before turning down the VARIAC, turn on the room lights and allow the students to see the vibrating rope "without strobe". - AL)
- video - Dancing Flames (Ruben's Tube)
(I brought over large "Hydrogen" regulator over from Physics to dispense Methane from our cylinder in Nau. - AL)
- Chladni Figures
(I transported the blue square, blue circular and black circular plates, mechanical vibrator, sand shaker and patterns guide to Nau. - AL)
- video - Breaking a Wine Glass
(I transported power amp, both horns w/ capacitors and stands, plastic enclosure, strobe and blue camera with posts and clamps to Nau hall via Gorilla cart wagon. I brought one Marquis and two Bohemia "fat" wine glasses. We ended up breaking the Marquis during lecture. - AL
