Broken glass (picking it up with a wet paper towel)

If you drop a glass on the floor and it breaks into a thousand little pieces, take a broom and clean it up first which takes care of most of the splinters. The tiny splinters can be removed with a wet paper towel, take a few though, so that you don't cut yourself.

Then just use a flashlight and check if you can still see little splinters on the floor, but you probably won't as it's all gone.
