Rio ready for Olympics 2016 opening ceremony

The Olympics in Rio de Janeiro, Brazil, will begin with a massive opening ceremony at the Maracana Stadium on Friday.

A total of 206 countries will be marching in the ceremony, as well as a team of refugees.

There'll also be lots of dancing and music - but the exact details are being kept a secret.

Ricky has made the trip to South America and will be covering all the action for us.
