My sister-in-law is visiting from out of town and showed me how to make Goop with Anya yesterday! Cornflour and water folks... apparently you can add food colouring or glitter etc.. but I like hosing just the natural products onto the lawn without any extras. Anya had a ball! What an easy, in-expensive activity. Great for tactile stimulation as it is hard and soft all at the same time... Try it and you will know what I mean. Very cool.
