Kids at a school in the south of England have spent all term building a model of London as it was in the 1600s - now they're going to burn it down.
It's being done very safely and is all part of their lessons about the Great Fire of London.
It might seem a bit crazy, but it's something the pupils are unlikely to forget and will hopefully help them to remember more about the subject.
So what has been the coolest school project you've been involved with?
Have you been part of a record-breaking attempt or invented something great?
Do you think cool school projects help you understand subjects or are they just a waste of time?
