Speed of light adventure

Did you know that the speed of light was first measured with reasonable accuracy in the Age of Enlightenment around about 1676?

I have a plan to do a garage science project in which we will directly measure the speed of light within the walls of Alan's Laboratory! Stay tuned for that one...but don't hold your breath on how fast it will appear.
