In this video I use Carl Sagan's own words against him by showing through repeatable scientific visual proof that an object further from a light source causing a longer shadow does not mean that the surface needs to be curved. 

If you want to do this experiment yourself inside or outside go for it. Light is a constant so this is an impossible experiment to falsify. This video shows how mainstream science is able to lie to generations of people. This test is so simple to do and shows that this test does not prove a flat or curved earth despite Sagan and other fake teachers saying it does. 

The truth hurts but the truth is all there is!
