The creative Georello Basic construction set allows children to learn some simple principles of mechanics while having lots of fun. Start by building a base of your choice with the interlocking plates. Then, using the connectors provided, fit the gears together so that they will all move at the same time. Next, decorate plates and gears with the brightly coloured pegs, and finally get a spectacular chain reaction by turning the crank to set everything in motion. Georello Basic is made of soft, washable plastic with rounded edges and is durable and completely safe.\r\nContents:\r\n\r\n48 pegs (15mm diameter) in 6 different colours\r\n4 middle gears\r\n4 small gears\r\n1 large gear\r\n10 interlocking plates\r\n14 white connectors\r\n1 crank
