The Science of Seeing and Hydraulic Science STEM kits

Both kits were gently used. If you have a STEM geared kiddo, these are for you! Learn all about science and explore how your senses work with these interactive kits. Hydraulic of Science includes a fully put together Digger Model that works and moves by pushing on the included syringes. The science of seeing is mostly unused, with most of the projects not used. Periscope and pinhole camera are not included in the kit. Originally paid $50 for the sets, asking $20.
