1. Make play dough? We have plasticine, but I want some softer playdough stuff as well. Ideally a really simple recipe that I can show the children and then they can make their own whenever they want it. Coloured would be great. 2. Colour raw rice/pasta? To put in sensory tubs and use for pictures mainly. I can see adding food colouring would work, but won't the rice/pasta go soggy? Any ideas gratefully received. Thank you!
