Hoop and Pen
From UO Physics Demonstration Catalog
Return to Newton's Laws
Description:
Balance a pen on top of a hoop which sits on top of a narrow necked bottle. Quickly pull the hoop away and the pen will fall into the bottle. A variation of the table cloth and china trick, this is a much easier demo but take note, it does require a practiced hand.
