We may never know the exact number of times it took Edison to perfect the light bulb (some say he tried up to 10,000 times to get it right) but one things is for sure- the light bulb IS an interesting object.
Although traditional incandescent bulbs are going the way of the Dodo bird, you can still hone your inner Edison by attempting a science project on electric light bulbs. Check out THIS article for tips on how to complete your own experiment, whether it is just for fun OR for an official science fair project.
