What’s it about?

The story.

Ada Twist is a scientist through and through: she asks why, forms a hypothesis, gathers data and tests everything. She's busy investigating why hot coffee smells stronger than iced, and taking part in the Great Backyard Bird Count, when a real emergency lands in her lap. Rosie Revere's Uncle Ned has drifted off into the sky in his famous helium-filled pants, and it's up to Ada to bring him safely down. Working through the problem step by careful step—and borrowing some of her brother's equipment—Ada must turn Uncle Ned's runaway buoyancy into the very thing that saves him. From the bestselling team behind Ada Twist, Scientist, this illustrated chapter book puts the scientific method at the heart of a delightfully silly adventure. David Roberts's illustrations bring the runaway pants and the whole gang of Questioneers to life, while Beaty slips in real vocabulary and ideas that make science feel like the most exciting game in town.

Why it lands

Why they love it.

Why kids love it

A grown-up floating away in helium trousers is exactly the kind of absurd emergency kids adore, and it's the smallest scientist in Blue River Creek who works out how to get him down. Ada's brain is the superpower here.

  • Secret skill
  • Proving yourself
  • Making a difference
  • Trickery and cleverness

Why parents love it

Beaty threads genuine science vocabulary and reasoning through a plot silly enough to keep any reader turning pages. Short chapters and generous illustrations make it a confidence-builder, and Ada is a wonderful model of a curious, determined girl.

  • Educational for adult too
  • Shared humour
