Feasibleness Puns

Two NASA engineers were arguing over the feasibility of building a high tech satellite that could see everything, anywhere in the galaxy, by orbiting a spherical lens around a mirrored device at various ranges of orbit. An application controlling the length of the O-Range (range of orbit) would pull the lens in, then release it, and centripetal force would pull it out again. The length of the "app pull", the distance the application would pull the lens back from orbit, had to be precise to ensure proper visibility at all times.

One of the scientists argued that the math to ensure total visibility at all times did not work. Eventually, they brought in another scientist to settle the argument. After several moments reviewing the math the two scientists had done on the board, their colleague spoke out.

"It's so obvious why you two cannot come to a conclusion," he said, "you're comparing app pulls to o-ranges!"

OK so as a dad who enjoys challenging his kids I would like some help. Shoot me your best feasible hiding spot for the Golden Egg on Easter...I'm thinking submerged in a hollow block or randomly dug hole just to fuck with the kids and their parents!
