What goes up must come down... eventually. Unless you are on Saturn's moon.
In the grand finale of the Agent 00-Gravity series, Barnaby Bumblespace faces his heaviest challenge yet. The villainous Major Mass is hopping between Saturn's moons, changing the gravity to turn the solar system into a chaotic pinball machine.
Barnaby must chase him across the icy geysers of Enceladus and the smoggy skies of Titan. But with gravity changing every five minutes, Barnaby doesn't know if his next step will be a tiny hop or a giant leap into orbit.
In this bouncy STEM adventure, kids aged 7-13 will learn:
- The difference between Mass and Weight (and why they aren't the same!).
- How Low Gravity affects movement (and jumping!).
- Why Saturn has so many moons and rings.
Packed with zero-G antics, magnetic boots, and a satisfying conclusion to the series, Moon-Hopping and Gravity-Dropping is a leap of faith into science fun.
