Here is an improved improvised artificial horizon. This generation still uses water and a plastic black coffee can lid as a backdrop. The lid is punched all around the edge so that water can freely communicate to the inner surface. This seems to level and decrease the time for a disturbed surface to settle. A smaller water container that is just larger than the lid seems to help centering.

Improvised Artificial Horizon
From: Greg Rudzinski

A mornings worth of CN trials with various improvised artificial horizon fabrications ended successfully with a square plastic container half filled with water that has a black plastic coffee can lid floating just at the surface. The black plastic lid seems to dampen out surface waves within the container. Results have been good (better than 2 moa). If in freezing conditions then I suggest substituting vodka for water ;-) Oil is better than water but messy.
