A kid can spend only so much time in “Isn’t that pretty, don’t touch, be quiet” museums. Parisian families looking for rainy-day activities where kids can be themselves head to the Discovery Palace. Located in the western wing of the Grand Palais, this hands-on science museum has exhibits and experiments on everything from chemistry to life sciences to the stars. Watch as real scientists test their theories, play fun math games, and challenge your memory. It's fascinating to explore the subjects that your little scientists are most drawn to, or to uncover the ones that make them want to run and hide.
