I was fixing my laptop, and as you may know, laptops have a lot of small screws to take out when you are fixing it. One of the screws fell into the floor (the floor has carpet on it), and I was unable to follow the screw with my sight. If I don't follow the screw with my sight when it falls, there is a high chance that I will not see that screw again.

My question is: what kind of method, tool or hack can I use to find small screws that falls into the floor?

I have tried using the tool with a magnet on the tip, that mechanics use to grab wrenches that falls in inaccessible areas, but had no luck finding the screw.
