PLEASE REQUEST DEMOS WELL IN ADVANCE

Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

Several clips within an AVI video file are provided above, one with an elastic collision of air hockey pucks and one of black and white beans being shaken in a Pyrex glass tray. The clips are shown in forward and reverse motion. Ask students to tell which clips are forward and which are reversed. The clips preview is given below.

Physical demo props are provided as well, including a pair of AirPro hockey pucks (or soccer balls) and an actual tray with two sets of different colored beads.

Hints:

To separate the blue and white beads after mixing them up drop them in the water. The blue beads sink and the white float.
