1D50.33 Carnival Ride: Carry a Ball

A ball is placed in an inverted wine glass and it rotates around the inside at a constant height when the glass is swirled at the right frequency

A hand holds a wide-mouthed wine glass upside down by the stem. A lavender-colored ball appears suspended inside the wine glass, pressed against the rim and side. It is easy to deduce that the ball is spinning inside the glass. A hand waits about a foot beneath the glass, ready to catch the ball if necessary.
