LOVE THIS. LEGO female scientists characters and backgrounds!!! A fantastic way to acknowledge and encourage girls in science. Unfortunately, this was a limited run product for LEGO and, not surprisingly, it sold out almost instantly. I had been searching for it for months.Here is the description from the LEGO site:The Research Institute has everything that you need to explore the world below, around and above us! Created by real-life geoscientist, Ellen Kooijman (alias:Alatariel), and selected by LEGO® Ideas members (formerly known as CUUSOO), this collection of scenes depicts three varied professions within the world of natural science. Help the paleontologist study the origin of dinosaurs with the magnifying glass, map the skies with the astronomer and her telescope, and assist the chemist as she carries out experiments in her lab. This set also includes building instructions, as well as a booklet containing information about the creator and an introduction to each of the professions featured in the set. There’s a whole world of exciting professions out there to explore – build and role play them to see if they suit you! Includes 3 minifigures: paleontologist, astronomer and a chemist.”What the description pointedly does not say is the minifigures are women. It is a fantastic product but, as I said, it immediately sold out and never continued. I find this so very odd. Again from LEGO’s site: “This set was overwhelmingly popular and is no longer available for purchase.” But, but… if it was overwhelmingly popular…why not continue it?All this being said. Grab one for your daughter before Amazon runs out!!!!
