Squirrel in the museum
(Book)

When Twitch hears that the school children are taking a field trip to the science museum, he decides he wants to join in the fun--so he stows away on the school bus and hides in a backpack to get in. But as always, not everyone is glad to see a squirrel in their midst. Pursued by security guards, Twitch turns the exhibits into his own private carnival rides--swinging on a Foucault pendulum, riding a model Mars Rover, and skittering across the Bernoulli air pressure table. Just when it seems like there's no escape, Twitch's chaotic romp turns up some surprises for the museum staff. . . . and a friendly boy in a wheelchair saves the day for the squirrel, sneaking him back out. For aspiring scientists, Squirrel in the Museum also includes an explanation of the scientific exhibits Twitch encounters--as told by the friendly science lab geckos.
