An ashtray being used as a nest (also good are stout drinking glasses, science goggles, rolls of duct tape, cozy room corners, and "udder-pots")
This sequence shows proper hand position and plunging technique, which is essential for the higher notes. Matching thumb to thumb is useful for getting a handle on the entire udder.
The tiny picobot in action.
