Last night I finally finished building my Lego Science Tower. The set is not official but originates from a crowd-funding effort by Bricklink. The sealed box had been sitting in my office for two years until I recently brought it home to have some fun with it.
You can see Newton's apple in the tree and Mendel's garden in front of the tower. The telescope on the top rotates and tilts by turning the knobs. Inside there is Pawlov's dog, Schrödinger's cat, a library and a chemistry lab, among other things. Overall a lovely design with ingenious attention to detail!
