One summer my father and I hopped the fence into the yard, and we did something I had always wanted to do: build a crop circle. Together, we used a plank of wood and rope to make a simple circular shape embedded in the grass. To our surprise it worked! In disbelief we laughed, and I bought a cheap drone and sure enough – it was visible from the sky. Together, with this circle, we sent a signal into space. In time, the land mark slowly faded and the grass returned, hiding our secret.
