Foot-Operated Water Sprayers C

Description

You have to use all your physical strength to be able to transport water from a low level to amuch higher one using the spiral cone. The running drum can be positioned at differentheights, at the bottom to “screw" water upwards or at the top to convey water from thebottom to the top. This special Archimedes Screw therefore has a similar effect to “Davidversus Goliath” : David’s strength is concealed; the screw reaches far down into a wellwhile Goliath impressively displays his entire strength.
