Everyone has their thing. Some people are dreamers. Some people are practical. Some people like to invent things. Our heroine isn't sure what her thing is. But she knows she has a lot of questions, like could she be faster than her own echo? If she built a giant paper boat, could she sail the sea? And how strong would she need to be to launch another kid into orbit from a teeter-totter? Eventually, she learns that all her questions have to do with one thing: physics!

In this thoughtful and gorgeous ode to the search for knowledge and finding one's passion, phsyics becomes a way for our heroine to ponder the magic of the world.
