If you don't have a dustpan on hand and need one right away—like if you broke some glass—you can make a quick one by cutting into a milk jug.
All you need to do is cut the bottom of the milk jug out, at an angle, so you have room to sweep in the debris. It isn't as good as a real dustpan (which are cheap, so just buy one already!) but it'll work if you're in a bind and need to sweep up a mess. Hit the link to see more.
