What if your job was riding waterslides?

It sounds like the best job in the world — and for thirty seconds at a time, it is. But before any waterslide opens to the public, someone has to ride it. Again, and again, and again. Someone has to feel exactly where the curve grows too tight, where the water layer goes thin, where a body shifts in a way a designer in an office could never have predicted. That someone is a waterslide tester.

This nonfiction career-exploration book introduces young readers to one of the most surprising jobs in the world — equal parts adrenaline and physics, joy and rigor. They'll discover what testers actually do (it isn't just sliding), how the thin layer of water on every slide is the single thing keeping a ride from becoming dangerous, why testers have to ride the way ten-year-olds really ride (sideways, arms crossed, holding hands in tubes), and why some of the most important work in the world is work no one ever notices got done.

Inside this book:

The five critical things every tester checks on every ride
A real day in the life — from 7 AM at the empty park to the signed certification at 4:30 PM
Famous waterslide testers in history, including Tommy Lynch's four years and 108,000 miles of slides
A glossary of tester words — banking angle, hydroplaning, flow rate, transition, and more
Hands-on experiments any reader can try at home
The book's heart: safety and joy are not opposites; they are the same thing

For ages 10 to 14, with insights and surprises that hold attention well beyond. A book for the kind of child who notices things — and for every parent or teacher who wants to show them that careful, quiet work matters, even when no one ever knows your name.
