Amaze your friends with water that flows uphill! | Viewer Challenge
Have you ever wondered how water can flow uphill? It’s not magic, it’s science. Alec and Jack complete the Compact Science Viewer Challenge for the “Pascal's Law at Work” episode exploring the science of Archimedes’ Screw Pump!
The Archimedes screw is a positive-displacement pump which traps fluid from a source and then forces the fluid to move to a discharge location. The Archimedes screw is made up of a hollow cylinder and a cylindrical core. The core sits inside of the hollow cylinder. Helical blades (the plastic tubing in our experiment) are wound around the core. When you bend the tubing into a spiral shape, it forms individual pockets where water can get trapped because the tubing curves upward on both sides. As you rotate the screw it traps alternating pockets of air and water, and the individual pockets move up the screw to the upper container.
Be sure to watch the Compact Science episode- Explore Western New York’s Devonian Pascal's Law at Work: Unlocking the Secrets of Erie Canal's Navigation to discover more about the science behind Erie Canal's locks!
