Imagine being transported back in time to wherever you like.
You could see dinosaurs close up. Or maybe live in Ancient Egypt and see pharaohs and Egyptian queens?
Maybe you'd like to go back and see what your parents were like at school!
Scientists are using virtual technology to recreate historic buildings & people - like museums but much better!
So where would you like to travel back to?

If I could time travel, I would travel to the Shakespearian times so I could get to know the genius behind the works before he was famous and to take part in one of his plays - preferably the Twelfth Night for that's my favourite.

I would like to go back to the Roman times. Then I could see Julius Caesar and see real gladiator fights. And I could hear people speaking Latin and could hear how it sounds to speak Latin all the time. Maybe they could help me with my Latin...

I would love to go back to the Tudor times to see if it really was that smelly and if people really were that mean. It would feel horrible because they thought that women should work all day so I'd pretend to be a rich person. I'd like to meet Henry VIII and Elizabeth I.
