Top Ten Inventions

The Science Museum in London recently created a top 10 list of the most important objects invented in history. Here's their list:

• Steam engine
• V2 rocket engine
• Electric telegraph
• Stephenson's Rocket
• X-ray machine
• Model T Ford
• Penicillin
• Pilot ACE Computer
• DNA double helix
• Apollo 10 capsule

I thought I'd make a top 10 list of the inventions that are most important to me. Here's my list!

• Volkswagen (originally started by Adolf Hitler and Ferdinand Porsche!)
• acetominophen
• the personal computer
  
• the telephone (...including the cellular variety)
  
• movable type printing press (revolutionized the mass-production of books!)
  
• indoor plumbing
  
• World Wide Web
• plastic
• the Interstate highway system
• the piano
  

These are mostly off of the top of my head, and there are many more inventions for which I am very grateful, but I thought I'd stick to a short list of 10, just so I don't bore anyone. But I'm interested to know what YOU would choose for your list of 10. Go for it!
