 What happens at the second confrontation with the Saylor brothers?
"She checks down to the last dimension," Bob chortled, working with slide-rule and logarithm tables. "Now all we have to do is find out if she's made of tungsten, iron, quartz crystals, and cinnabar! Mr. Andrew S. Burnside, you owe us five hundred and fifty thousand dollars!" Moments later, they were outside the ship, with star-powdered infinity spread to all sides. Will pay $5.00 per ton. And if The Interplanetary Hauling & Moving Co., hadn't been about to go on the rocks (chiefly due to the activities of Saylor & Saylor, a rival firm) neither Bob nor Queazy would have thought of sending an answering ethergram to Burnside stating that they would fill the order. And yet, if by some chance there was such a rigidly specified asteroid, their financial worries would be over. Unfortunately, other interplanetary moving companies had cashed in on that brainstorm, chiefly the firm of the Saylor brothers—which persons Bob Parker intended to punch in the nose some day. Now that he and Queazy had found the asteroid, they were desperate to get it to its destination, for fear that the Saylor brothers might get wind of what was going on, and try to beat them out of their profits. Which was not so far-fetched, because the firm of Saylor & Saylor made no pretense of being scrupulous. Now they scuffed along the smooth-plane topside of the asteroid, the magnets in their shoes keeping them from stepping off into space. They came to the broad base of the asteroid-wedge, walked over the edge and "down" the twelve-foot thickness. By the naked eye, they could see iron ore, quartz crystals, cinnabar, but he had the spectroscope and there was no reason why he shouldn't use it. He satisfied himself as to the exterior of the asteroid, and then sent the twin beams deep into its heart. The beams crossed, tore atoms from molecules, revolved them like an infinitely fine powder. The radiations from the sundered molecules traveled back up the beams to the atomic-whirl spectroscope. Her expression darkened as she saw the completely instinctive way he was looking at her and her radioed-voice rapped out, "Now you two boys go and play somewhere else! I'll let the Interplanetary Commission know you've infringed the law. He and Queazy caught up with her on the side of the asteroid they hadn't yet examined.

 The yo-yo fails to hit the other ship, as it can't quite reach it.  The Saylor brothers call on the Interplanetary Commission for help.  The yo-yo worked as intended, hitting their ship with the first hit.  The yo-yo worked as intended after some maneuvering, damaging their ship.
