Min Makes a Machine — Emily Arnold McCully

One very hot day, Min, a budding engineer, builds a machine that draws water from a well and into a swimming pool.

Min wants to play, but Ann and Bess say it's too hot. Using a pipe, a tube, and some glue, Min makes an Archimedes screw, a device that draws water, to get water from a well into a swimming pool.

This book has the same characters as 3, 2, 1, Go! in which Min builds a catapult.
