Oersted's Effect
A current carrying wire will have a magnetic field directed by the right hand rule.

Odd-Shaped Bar

Different combinations of mass and distance are required to balance the torques on the odd shaped bar.

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.

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!).

Pascal's Vases
Water pressure is dependent on depth only. Thus, two differently shaped vases will show the same pressure at the same depth.

Pasco Synthesizer: Pure Tones
A synthesizer is able to produce 'pure' tones, each being a single sine wave.

Pasco Synthesizer: Chords
A synthesizer is able to produce 'pure' tones, each being a single sine wave. Different cords are created by adding tones.

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.

Person/Trash can drop
A person and a trash can experience the same acceleration when 'dropped'.

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.
