HOW? - How Things Work

Discover the mechanisms hiding inside everyday objects. A wheel, a computer mouse, a pair of scissors: you use them without thinking. HOW? invites you to look closer, with a daily discovery told through interactive exploded-view drawings. GUESS FIRST Start with a question and make your guess. Then reveal the answer and explore the mechanism behind it. TAKE IT APART Follow the numbered steps as the drawing comes apart. Each highlighted piece has a job: see what it does and how it works with the others. Try the interactive controls to explore further. BUILD YOUR LIBRARY Return to previous discoveries and look at familiar objects with fresh eyes. CHOOSE WHAT COMES NEXT Suggest an object you are curious about and vote for topics you would like to see explained. HOW? is free, with no account required, no subscriptions and no in-app purchases. Available in English and French, with light and dark appearances and optional reminders. One object. A few parts. Something new to understand.
