Tonight people across the county will stare at the Kent skyline oohing and aahing at the huge range of colourful displays.
But do you have any idea why we celebrate Bonfire Night?
Earlier today KMTV went down to Chatham High Street to test whether the public are bright sparks on the subject, or just a bit dim.

Most of the people we spoke to knew that Guy Fawkes had something to do with it - but expanding much further than that seemed to be a struggle for most.
Thankfully, history lecturer Tim Luckhurst was on hand to tell us the true story.
He said: "Bonfire Night's intriguing because it's about torture, it's about gruesome execution, and it's about high politics.
"When Elizabeth I died, and James I came to the throne, catholics in England hoped very much that they were going to get a much better deal than they'd got from his predecessor.
"They had reason to hope that, but it didn't happen.
"James couldn't afford to be nice to catholics so he began to persecute them in just the way that they had feared.
"So a group of catholics plotters decided that they wanted to end the King's reign and bring down his parliament."
