The packaging of this item is sun-bleached having been in the window for a wee bit too long. Inside is perfect though. The junior inventor kit is a fun way to get little humans experimenting and learning through play. Each kit contains 6 experiments; showing them how to make alsorts including a mechanical grabber, a crane and a climbing frog. Each experiment is carefully devised to teach them scientific principles, such as momentum, potential energy and conservation of energy. We particularly love how the elements can also be mixed up to conduct and invent wonderful new experiments and devises. Suitable for 4 years plus. how does it come wooden toolbox shaped box, 27 x 31 x 9cm
