The Consumer Product Safety Commission has been trying decide for weeks if science kits designed to teach children are safe enough for children to use without vigorous testing. It's not just the chemicals or sharp items in the kits that they are troubled with however. They are also concerned about the dangers of paper clips, magnets, and rulers. From the article: "Science kit makers asked for a testing exemption for the paper clips and other materials. The commission declined to grant them a blanket waiver as part of the guidance the agency approved Wednesday on a 3-2 vote." To be fair, paper clips can cause a lot of damage — just look at what Clippy did to Microsoft Office.
