Oersted's Effect	A current carrying wire will have a magnetic field directed by the right hand rule.	Real	Real MPG	E and M 5H10.20
Odd-Shaped Bar	Different combinations of mass and distance are required to balance the torques on the odd shaped bar.	Real	Real MPG	Mechanics 1J10.27
Organ Pipe; adjustable, closed end	As the piston is moved out, the standing wave that is set up inside the instrument lengthens, producing a lower pitch.	Real	Real MPG	Waves 3D32.15
Organ Pipe; open end	A standing wave (with an antinode always at the open end) is set up in an organ pipe when air is passed over a slit. Harmonics of this wave can be set up by blowing harder (a LOT harder!).	Real	Real MPG	Waves 3D32.10

Pascal's Vases	Water pressure is dependent on depth only. Thus, two differently shaped vases will show the same pressure at the same depth.	Real	Real MPG	Fluid Mechanics 2B20.42
Pasco Synthesizer: Pure Tones	A synthesizer is able to produce 'pure' tones, each being a single sine wave.	Real	Real MPG	Waves 3C50.10
Pasco Synthesizer: Chords	A synthesizer is able to produce 'pure' tones, each being a single sine wave. Different cords are created by adding tones.	Real	Real MPG	Waves 3C50.10
Person and Rotating Platform	Due to the conservation of angular momentum, when the rotating person brings the masses closer to his body, he will rotate faster. We have all seen this in figure skating.	Real	Real MPG	Mechanics 1Q40.10
Person/Trash can drop	A person and a trash can experience the same acceleration when 'dropped'.	Real	Real MPG
Ping Pong Ball w/Funnel	When a ping pong ball is placed in a funnel with the air blowing out, the ball won't fall out of the funnel. The rushing air creates an area of low pressure that holds the ball in place.	Real	Real MPG	Fluid Mechanics 2C20.35
