Beats; differential tuning forks
When we hear two tones close in frequency, we experience a vibrato or beat that has the same frequency as the difference of the two tones. For example, if one tuning fork is at 256 Hz and one is at 257 Hz, then we will hear a beat with a frequency of 1 Hz.

Bed of Nails
When the pressure is distributed over many nails, each individual nail exerts too small an amount to pop the balloon. When a less dense population of nails is used, each individual nail exerts more pressure and the balloon pops.

Bernoulli Envelope
Blowing air over the open end of an envelope causes the two sides to separate due to the lower pressure of the flowing air.

Bicycle Wheel and Rotating Platform
The force created by a turning wheel will cause the person on the platform to turn in order to conserve angular momentum. In this case, the wheel begins vertically and the person will rotate left or right depending on the tilt of the wheel.

Bicycle Wheel and Rotating Platform 2
The force created by a turning wheel will cause the person on the platform to turn in order to conserve angular momentum. In this case, the wheel begins horizontally. Turning it vertical makes the person spin, turning it completely over makes the person's speed double.

Bicycle Wheel Gyroscope
Outside torques produced by gravity and friction cause the wheel to be vertical and spin about the axle in order to conserve angular momentum. This is why it's easier to stay on a moving unicycle or bicycle than a stationary one.

Bi-Metallic Strip
Different metals expand at different rates when heated. One side of the strip is one metal and the other side is another. The higher expansion rate of the longer side causes the strip to bend when heated.

Boomerang (outside)
A boomerang will lift and curve when thrown. The lift comes from the shape of the arms and the curve comes from the spinning motion.
