1M30.30 Woodpecker

A toy bird slides down a rod at constant energy, giving up energy to friction as it “pecks” the rod. A “loose clamp” on the ringstand demo is also shown.

A small wooden "woodpecker" (complete with fuzzy red 'feather' cap) poses at the top of a thin pole. Next to the woodpecker is a table stand equipped with a ring clamp. Presumably, the ring clamp is loosely fastened so that it will 'jitter' its way down the stand's central shaft when nudged, but this is not apparent in the photo.
