1D40.21 Dry Ice Puck Dumbbell

Two dry ice pucks on the ends of a bar form a dumbbell that rides on a sheet of plate glass. Use a cue stick to hit it on and off the center of mass.

A glass sheet rests on a large table. Two metal disks that resemble top hats in appearance rest on the glass. A steel bar connects the two disks at their 'crowns'. A cue stick sits near the disks. A styrofoam container presumably holds dry ice in the background of the photograph.

Hitting at the center of mass.

Hitting off the center of mass.

Location: dry ice pucks D2-6, sheet of glass M6-5, dry ice (get from Chemistry Department), cue stick end of aisle A
