World's best inventions

My excessive use of wireless internet got me thinking as to the world's best inventions. I present a preliminary list, with lots of things I'm sure I'm forgetting.

In no order:

- Wireless internet: The ability to take the internet to class, to fields, and anywhere else you may like is pretty damn cool.

- The internet itself: no explanation necessary.

- The light bulb: my default answer. Think about how different things would be if still by candlelight.

- Soap: just to appease the medical world.

- Fire: Technically a discovery, and not an invention. But because it led to cooked food, it gets a mention.

- Birth Control: Idea courtesy of a friend, when he was asked the question. Self explanatory, really.

- The ball: Perhaps also a discovery, but I'm going to go with the first manufactured ball, with the intent to play sports. Fantasy geeks everywhere thank you.

This list is far from comprehensive- just starting the debate.

PUTFR,

Dis

Addendum: I've been told I forgot the printing press, and the combustion engine. Both good.
