Pneumatic Cylinder

We just learned about the Pneumatics.

One use for pneumatics is a Pneumatic Cylinder.

This is a type of tube that is filled with pressured air.
More air can be pushed into it to make something move like a pole because the air is pushing it out.

We've learned before about using water or liquids in machines called hydraulics.
Some people choose to use pneumatics instead of hydraulics because if there is a leak then it is just air and no water will drip on anyone.

One good example of this is the Tiki Room at Disney Land.
The people chose pneumatics to do the movement of the birds and plants, and if there is a leak it won't make a mess for when the people are watching the show.
