F1-12: PASCAL'S LAW - COILED TUBE PARADOX
- ID Code: F1-12
- Purpose: Illustrate Pascal's law in a dramatic way.
- Description: Referring to the photograph on the right, pouring water (colored green) into the tube at the left in the photograph causes the asymmetric configuration shown due to the equalization of pressure in the central air bubble. Similarly, if one end of a three-turn loop of tubing is raised vertically, as in the photograph at the left above, water poured into the high end will never come out the bottom end, even when the bottom end is lying flat on the table, as seen in the left photograph.
