WITHITs - What in the heck is this?

Spring Meeting of the Illinois Section of the AAPT
April 4-5, 2008 - University of Illinois, Urbana-Champaign, Illinois

Do you have something in your storeroom that has you baffled?   Please bring it, place it on the designated table (with your name) so we can all look at it during the Breaks.  Please use the Registration form to tell us that you will be bringing an item.  We will provide some time for the audience to figure out what these things are near the end of various sessions.  Those who have signed up so far are listed below.  It should be fun!
