You can now experience a part of the Smithsonian collection from anywhere with just a 3D printer. I could see this being a great tool for teachers!
Via lifehacker :
The Smithsonian’s network of museums offer 3D renderings of some of its collection, and more importantly, plans so you can 3D print some of those items at home using your own 3D printer.
Artifacts available for printing range from things like fossils to a replica of Abraham Lincoln’s head.
