If you could travel back into time, and take any 21st century item back with

you, what would you take and why?
My list:

1. Ipod (lot's of batteries too)
2. lap top with extension cord for recharging.
3. Cell phone.
4. Ford Mustang! ( ^ _ ^ )
5. Motor cycle
6. Taser ( ^ _ ^ ) Never know when you might have to tase someone.
