Nursery children enjoyed making ‘rainbow slime’. They worked in pairs to make yellow, pink, green, blue and purple slime. The children noticed the changes in the mixture as they added different ingredients to it. They mixed the slime until it was malleable and no longer sticking to their fingers. The children had a go at stretching the slime as far as they could across the table. They used words such as ‘slimy’, ‘slippery’ and ‘cold’ when asked how the slime felt.
