Getting a closer look at the inner workings of a Dynamometer Car
Derby Museum will be braced for impact on Friday February 19th.
Its curators will be hoping for a friendly invasion of folk wanting expert opinions on the objects they'd like to add to the BBC's big History of the World collection online.
BBC Radio Derby's mid-morning show will be live from the museum, with Rams commentators Graham Richards and Roger Davies among the guests.
Meanwhile at the Silk Mill a huge star-dome will bring the skies to life.
The whole enterprise began with the launch of the British Museum's list of 100 objects, chosen to tell the history of this country and its relationship with the rest of the world.
On a local level, BBC stations got together with their neighbourhood museums and selected their own lists of ten.
Now it's your turn to swell the ranks of interesting exhibits - and Friday February 19th is designed to give you a hand.
If you call at Derby Museum between 11 and 3 on that day there will be curators poised to discuss your object and help you upload it onto the BBC website.
Former Rams commentator Graham Richards will be adding his own objects to A History of the World
The curator of Creswell Craggs will bring his chosen item: a 60 thousand year old flint handaxe. And just to prove how skilled Neanderthal man actually was, a modern-day flint-knapper will be doing demonstrations.
Rams commentators-extraordinaire Graham Richards and Roger Davies will be bringing memorabilia from their involvement with the Beautiful Game, and doubtless be up for a chat.
Three of our area's list of ten are actually housed in the museum: Erazmus Darwin's microscope, the first-ever accurate map of Derbyshire, and Joseph Wright's painting of a fascinated group of listeners clustered round an orrery - a mechanical solar system.
Down at the Silk Mill a huge inflatable star-dome will do its best to add to our current understanding of the universe. Then, while you're there you can cast an eye over two more from the top ten: Rolls Royce's Merlin engine and the Handyside post box.
It's all free: just earmark the day in your diary and be part of the story that is A History of the World.
