Ada Twist and the Perilous Pants (Questioneers #2) by Andrea Beaty

Ada likes science.  She learns what she can and then she experiments.  Her brother isn't very happy when she experiments with his tennis shoes.  She was testing the way hot and cold worked on smells.  Hot made it smell worse.  Before she can go on to another test, her girlfriend shows up and tells her that her Uncle was wearing his helium pants and the guy holding the rope lost it and now he's floating around town.  Can Ada help get him back down?

Amulet Books sent me a copy of this book for review (thank you).  It is being published today.

The firemen try to come to the rescue but he's just out of reach of their tallest ladders.  Ada finally comes up with an idea but she's no good at getting the tennis balls where she wants them.  Will she able to save him or will he float out to space?

Science is exciting with Ada!
