In the time machine--surprisingly easy to construct--Max and Boomer bump around to the past and the future, tangle the string of time, and crash into the ancestral houseboat, promptly sinking it. And in the past, the vase remains intact. Disheartened, Max and Boomer return to the moment just before their adventure began, to warn themselves NOT to build a time machine. In spite of the warning, Max tosses a Frisbee for Boomer, directly in the direction of the vase, and their wild adventure begins again, and again, and again...

Joyful and uproarious, this is a one-of-a-kind circular tale that plays on the perils of time travel.
