Our first pictures were glue and lot and lots of glitter.
So step one is use glue to create you firework scene.
Sprinkle wet glue with salt and then shake of spare salt.
Then dab the salt/glue mixture with the water colour paint and watch the paint spread out.
The finished work.
I asked if they wanted to have a go painting with the remaining water colour paint, which they did, one loved just seeing the paint merge together and then mixing it to make lots of different shades of brown.
