Okay. Here's an experiment you can perform: Get a small Styrofoam cooler, an old cell phone and a weather balloon. Drill a hole in the cooler, and position the phone's camera out the hole. Set the camera to take pictures every ten minutes, and upload the pictures to the internet. Attach the weather balloon, and fill it with helium.
Alternatively, go to the observation deck of a tall building.

I challenge you to take a telescope to the beach and experiment.
Have a friend drive a boat out of range where you can't see them and they go over the horizon. Then use your fancy telescope and wala.
