The BBC broadcast truck spent the morning at Our Lady's Convent High School in London on Friday 24 November 2006 for a live interview about students' visit to a school in China.
The van looked big on the outside but it contained so many wires...
... and screens, that the truck was tiny on the inside!
There were lots of screens, which meant you could watch different clips at the same time and rewind one tape while you were watching another.
We were really happy to have seen what goes on behind closed doors.
