Things to do with a slice of bread (besides eat it)

About 8 months ago I started reading Reader's Digest's Extraordinary Uses for Ordinary Things: 2,317 Ways to Save Money and Time. It sounds like something I would be interested in. It's a reference book, so it's a very slow read. There are several things I come across that I think "Everyone knows that trick, don't they?" or "Wow, that's a lot of work to create something very tacky." or there are a few that I found don't work like the book claims they do. However, throughout there are some good ideas. This weekend I came across a couple with bread that actually seemed helpful, plus I added one of my own.

• Soften up hard marshmallows. Put marshmallows in a seal-able container with a couple slices of bread. Leave it alone for a couple days and remove the bread. The marshmallows will have absorbed the moisture from the bread.
• Soften up hard brown sugar. Same idea.
• Pick up glass fragments. After picking up the big shards, press a piece of bread over the area to pick up all the tiny slivers. Just be careful as you're throwing the bread away.
