Bicuspid Castle

British children are being asked to donate their baby teeth to a combination art-and-science project called Palaces, in which the teeth will be used to decorate a magic castle. The sculpture will then go on exhibit to spotlight the ways in which even parts of our bodies can be reused and recycled, specifically, in this case, the dental pulp in baby teeth being a source of stem cells. I don't know whether they will accept teeth from other countries, but here's the link, in case you want to try(!) or just learn more about it: http://www.palaces.org.uk/
