I got a new science set for Lea Clark to conduct experiments with. It was a Christmas gift from Our Generation. The set is called Under the Microscope. It comes with a many items including a microscope with a working light, test tubes, a beaker and safety goggles that fit your doll perfectly. Our Generation is sold at Target, but they may have retired this set. I know you can still get it for under $20 on Ebay. It is very realistic and a great set for your American Girl dolls.
