We've all been in that situation where we drop something very small — like a screw or other important piece of something — on the ground and it rolls away. Tips-and-tricks website ClueDB has a trick for finding them quickly.
It's obviously a little more clever than "use a torch to find things in the dark". ClueDB user @panicboy lets us know that if you angle the torch correctly, you'll make it a lot easier to find whatever it is you dropped:
Use a flashlight held parallel to the floor to search for dropped objects - the long shadows will make them easier to find. If necessary, turn off the lights first.
It's a pretty clever way of finding that stuff without scouring every inch of your kitchen floor.
