Water Leveler

Description

This cylindrical gravitational field detection system uses only water to indicate earth’s gravity center. The straight line surface display provides the baseline of a perpendicular line that intersects with the center, and therefore the technical definition of “up” and “down” used in virtually every scientific and architectural application.

When used with optional motion mode, Water Leveler can also indicate momentum and inertial conditions. Using only Newton’s laws, the user can calculate direction and velocity relative to earth’s center.
