From DragonflyTV. Aaron and Tevi are really into exploring the science of places like the Egyptian pyramids and England's Stonehenge. They wanted to figure out how one man moved all of the massive stones to make Coral Castle. They knew he used simple tools so they built a similar set-up, using a fulcrum and lever. Then they built a tripod with a block and tackle system (pulley), also based on the original design, to see if it could lift the huge limestone blocks off the ground. The vi
