DIY Experiments
Laser Over Water Experiment
Set up a laser pointer at water level across a large lake. The laser should curve with the Earth, but it remains perfectly straight, proving flat water surface.
Equipment: Laser pointer, tripod, measuring tape
Best conditions: Calm water, night time, 3+ mile distance
Water Level Tube Experiment
Use a long clear tube filled with water. No matter the distance, water finds its level perfectly flat, disproving the curve.
Equipment: Clear tube (100+ feet), water, food coloring
Expected result: Water remains level regardless of distance
Bring Back the Ship
Watch a ship "disappear" over the horizon, then zoom in with a telescope or camera to bring it back into view. This proves it's perspective, not curvature.
Equipment: High-zoom camera or telescope
Key observation: Entire ship returns, not just the top
Gyroscope Test
A gyroscope maintains its orientation. On a spinning globe, it should precess 15° per hour. High-precision gyroscopes show no such movement.
Equipment: Precision gyroscope, stable platform
Expected on globe: 15°/hour drift. Actual: 0° drift
