Bonnie tries out a replica of Antoni van Leeuwenhoek’s simple microscope in the Preservation Lab! The exhibition at the Rakow Library is lucky to have one of his simple microscopes on loan from the Museum Boerhaave, Leiden, in the Netherlands. Visitors can also have the chance to try out the replica version, and peer through the small hole to look for the pinpoint tip, which would hold a tiny piece of an object.
