Try these fun and easy experiments at home to show that the earth is flat!
Test that things fall
What You'll Need
- a rock or other suitable object
Instructions
- hold rock in your hand
- extend your arm out at shoulder level
- release rock
What is happening?
You notice that that when you release the rock, it falls. This shows you that objects simply fall. There is no need for a complex theory, things will simply fall when released. Try with various other objects for further experimentation.
The horizon is flat
What you'll need
- camera
- printer
- ruler
- pencil, pen, or other writing utensil
Instructions
- take an unobstructed view of the horizon such as over a large body of water or a field
- print your photo on a home printer or at a print shop
- place your ruler along the horizon line
- draw a line along the ruler and horizon with your pencil
What is happening?
When observing the line you draw along the horizon, you can see that the horizon is flat. This is because the earth is flat. You can repeat this anywhere on earth, including from an airplane with the same results.
A ball won't roll
What you'll need
- a ball
Instructions
- place the ball on the floor or ground
- observe where it stops moving
What is happening?
When you place a ball on the ground, you can see that while it may roll a short distance, it will eventually stop. This is because while the surface of the earth has small ups and downs (or large ones in the case of mountains), the ball will eventually come to rest because the earth itself is flat. Much like the horizon line, you can repeat this the world over with the same results.
