Hundreds of thousands of protesters have been out in Cairo, Egypt's capital city. It's the biggest demo they've had since the protests started over a week ago.
The country's army has been out on the streets, but they've said that they won't use force against the demonstrators.
Men, women and even small children have all been taking part in the demos.
The protesters want Egypt's president, Hosni Mubarak, to resign.
They're unhappy with the poverty and problems the country has had while he's been in charge. He's been president for 30 years.
An extra plane is being sent from the UK to bring back British tourists who want to leave Egypt and not get caught up in the demos.
People have been singing and chanting whilst demonstrating and some have even painted their faces with the Egyptian flag. Protests look set to continue.
