Important guests like family friends, grand-parents or OFSTED inspectors will be very impressed by a cup of coffee made from beans ground by your young charges. Show children how to turn the handle slowly and to separate the beans with a chopstick or toothpick during grinding (when the noise stops, the beans are lodged). The smooth circular movements enhance motor skills - their sense of achievement & pride when the cup is served is wonderful to see. Dimensions (cm): 17.5(h) x 12.5 (dia)
