Flat Earth Experiments You Can Do Yourself
Don't take our word for it - test Earth's shape yourself with these reproducible experiments. Each test is designed to be performed by anyone with basic equipment.
Laser Level Test Over Water
EasyThis classic experiment tests whether water curves over distance. According to the globe model, water should drop 8 inches per mile squared.
What You'll Need:
- Laser level or laser pointer
- Tripod or stable mount
- Target board (white poster board)
- Measuring tape
- Calm lake or bay (3+ miles across)
- Helper at opposite shore
Steps:
Bring Back the Ship Experiment
EasyTest whether ships really disappear "over the curve" or if it's just a limit of human vision.
What You'll Need:
- Telescope or camera with powerful zoom (50x+ optical)
- Tripod
- Ocean or large lake viewpoint
- Clear day with good visibility
Steps:
- Find a ship that has "disappeared" over the horizon to naked eye
- Set up telescope/camera on stable tripod
- Zoom in on where ship disappeared
- Continue zooming - the ship will come back into full view
- Document with photos/video
Expected Results:
Ships that supposedly went "over the curve" can be brought back into full view with zoom. This proves they never went over any curve - they just went beyond the limit of human vision.
Frozen Lake Experiment
MediumIn winter, frozen lakes provide perfect flat surfaces to test for curvature over long distances.
What You'll Need:
- Theodolite or auto-level
- Measuring poles with markers
- GPS device
- Frozen lake (10+ miles)
- 2-3 helpers
Steps:
- Set up theodolite at one end of frozen lake
- Have helpers place poles at 1-mile intervals
- Level the theodolite and sight each pole
- Record the readings - all poles should read level
- Calculate expected drop using 8" per mile² formula
- Compare actual readings to globe predictions
Safety Note:
Always ensure ice is thick enough for safe travel. Work in groups and carry safety equipment.
Expected Results:
All poles will read at the same level, showing no curvature. At 10 miles, globe earth requires 66 feet of drop - but measurements show perfectly level ice.
Salt Flats Observation
EasySalt flats like Bonneville provide massive flat surfaces to observe distant objects that should be hidden by curvature.
What You'll Need:
- Vehicle access to salt flats
- Binoculars or telescope
- Camera with zoom
- GPS for distance measurement
Steps:
- Drive to center of salt flats
- Identify distant mountains or structures
- Measure distance with GPS
- Calculate how much should be hidden by curvature
- Observe and photograph - entire objects remain visible
Expected Results:
Mountains 50+ miles away remain fully visible from base to peak. On a globe, thousands of feet should be hidden behind Earth's curve.
Gyroscope Test
HardTest for Earth's alleged rotation using a precision mechanical gyroscope.
What You'll Need:
- Precision mechanical gyroscope
- Stable mounting platform
- Compass for orientation
- Timer
- Documentation materials
Steps:
- Set up gyroscope on stable, level platform
- Spin up gyroscope and note initial orientation
- According to globe theory, it should precess 15° per hour
- Monitor for several hours, documenting any movement
- Compare results to globe model predictions
Expected Results:
Many independent researchers find no 15°/hour drift, suggesting Earth is not rotating. Results challenge mainstream claims about Earth's motion.
Document Your Results
When conducting experiments:
- Record everything - photos, videos, measurements
- Note weather conditions and visibility
- Have witnesses present when possible
- Share results with flat earth research community
- Repeat experiments multiple times for consistency
Important:
True science requires honest observation. Record what you actually see, not what you're told you should see. Trust your senses and measurements.
