WITHITs - What in the heck is this?

Spring Meeting of the Illinois Section of the AAPT
March 30-31, 2007 - Western Illinois University, Macomb, 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.  If there are enough, we will schedule one or two sessions for the audience to figure out what these things are.  Those who have signed up so far are listed below.  It should be fun!
