I made the X-ray machine using a clear tote (Wal-Mart), and an under the counter enclosed flourescent light bar (Home Depot). I used velcro Command Strips to hold the light inside and on the wall. Once we are done with our Pets theme, I plan to set it on a table and use it as a homemade light table! The x-rays came from http://www.discountschoolsupply.com
