A variant of the Archimedes' screw can also be found in some injection molding machines, die casting machines and extrusion of plastics, which employ a screw of decreasing pitch to compress and melt the material. Finally, it is also used in a specific type of positive displacement air compressor: the rotary-screw air compressor.

Then simply place your screw with the bottom end resting in the water. Put a glass under the top of the screw. Then start turning the pipe! The water will travel up the screw and drip out into the glass! Pretty neat! Note that the water stays in the underside of the tubing. As you turn the screw, it scoops up some water, then air, then water, etc.

This is where Archimedes' discovery came in useful. First, Archimedes took a lump of gold and a lump of silver, each weighing exactly the same as the crown, and filled a large vessel with water to the brim, precisely measuring how much water was contained in the vessel. He then gently lowered the lump of silver into it.

2 Archimedes screws are generally used to transport material. An irrigation system is a good example of this mechanism. An Archimedes screw pump can be positioned over a reservoir. When it spins, water is pushed up the length of the screw to the end of the threads, where it is deposited, generally over an arid, planted land.

Place one end of your Archimedes screw in the lower container of water, and align the other end over the upper container. Rotate the screw so the bottom end of the tubing scoops water with each rotation. It should go underwater and then come back above the surface with each revolution, not remain completely submerged the entire time.

Step 3: Making Templates. In order to make the screw more efficient, we wanted all of the blades to be of equal size and pitch. To make the blades of equal size we simply cut a template out of wood by turning a cylinder of wood on a wood lathe, slicing it into discs then drilling through the centre.

This Archimedes' screw is such a neat science lesson about simple machines! We use screws all the time to hold things together, but screws are also used to raise and lower things.

However, gap leakage should increase with speed in Archimedes screw pumps.
