Wikijunior talk:How Things Work/Wheel

From the sources I've heard from, the first wheels were Sumerian potters' wheels. The potters found that the wheel could be rolled along when turned on its side, and wheeled carts came to replace the sledge. --Gray Porpoise 00:52, 14 November 2006 (UTC)

Danger of Wheels
I'm not familiar with the style guide for this book, but it strikes me as a bit silly having a how-dangerous for each and every 'How things work'. Here I'd sooner delete dangers, but if we must have them getting something caught coat, scarf etc in a turning wheel and being pulled into it is a danger of the wheel. Car accidents aren't really dangers from the wheel. They'd still happen if our cars were jet sleds. JamesCrook (talk) 17:55, 7 November 2010 (UTC)
