List of devices

Man-made devices, both manual devices and electrical appliances, past and present.

Pis forPeg

A peg is something you use to hold wet clothes to a line so it can dry after it has been washed. Modern pegs are usually made of wood or plastic and have a spring in them so they hold shut tightly.

Pis forPendulum

A pendulum is something heavy suspended from a fixed point on the end of a long, thin rod. Pendulums are swung backwards and forwards, and are commonly seen in old fashioned clocks like grandfather clocks.
A photocopier is a device that makes copies of flat images, like the pages from a book. Photocopiers used to only be able to make black and white copies but today many photocopiers can make color copies too.
A pipe is a device used to smoke tobacco, the same ingredient that is in cigarettes and cigars. Pipes can be quite ornate, and are more difficult to use than cigarettes.

Pis forPlough

A plough is a device for breaking up the soil in a field or garden before crops are planted. Ploughing the soil makes it softer and easier for plants to grow, and turns the soil over so any vegetation leftover from an earlier crop will go underground and add nutrients to the soil. Ploughs used to make one furrow at a time and were pulled by horses like in the picture. Today they can make dozens of furrows at a time and are pulled by tractors.

Pis forPlug

A plug is a small device, usually made from rubber, that is used to stop up the hole at the bottom of a bath or washbasin. When you are finished using the water, you just pull out the plug and let the water drain away.

Pis forPlunger

A plunger is a device made up of a rubber cup on the end of a stick. The cup is put over a drain and pushed up and down to break up blockages in plumbing.

Pis forPrinter

A printer is a device that you connect to a computer. Printers turn files that you can only see on the computer's screen into printed images on a piece of paper.
A propellor is a type of fan that is used on planes and ships to propel them forward. Sometimes a propeller is called a screw.
A protractor is a device used for measuring angles. You can get protractors as both half and full circles. Protractors are also useful for drawing angles.
