• The first official soapbox derby, held in Dayton, Ohio in 1934, was won by an 11-year-old - against 362 other racers.
• Red Bull's modern Soapbox Race has seen entries including a full-sized piano and a giant rubber duck.

An entire sport that started with three kids and some old soap boxes in 1933. Now it's your turn - pull back, let go, and feel stored energy turn into pure speed.

• Race on carpet, tile and the driveway to see where your racer's fastest.
• Mix and match carts and drivers for new combos, or build a second racer from spare parts to race head-to-head.

Test whether pulling back further always means going further, and chart your results. Then grab the free racer template from the Curiosity Hub and design your own totally original driver and cart.
