^* To inspire future generations to take up the fight against gravity, Babson paid for stone monuments to be erected at thirteen prominent American colleges. Colby College’s “antigravity stone,” as it became known, states its goal as follows: “To remind students of the blessings forthcoming when a semi-insulator is discovered in order to harness gravity as a free power and reduce airplane accidents.” The students were differently inspired: In what became a joyous progravity rite, the antigravity stone was knocked over so many times that the college eventually relocated it to a less prominent spot. Along with the stones, Babson left the colleges small grants but did not explicitly state that the money must go toward antigravity research. Loath to sponsor “Mickey Mouse” science, Colby used the money to erect a skyway connecting two science buildings. “At least,” noted a college spokesperson, “it’s off the ground.”
