Here is a great idea for helping to keep kids safe. This summer we came across a little girl at a street fair that lost her mom and dad. If she had one of these bracelets it would have been a lot easier to find her parents. (everything worked out well) You can make them out of beads, duct tape or disposable paper bracelets. If you make one out of paper you may want to cover it with clear tape so it makes it through a few hand washings.
This one is by Faces by Gina made of duct tape.
