For the base she used a cereal box which she glued a black paper cone onto.
She then painted it green while having a chat with Mark about her day at school.
Having been caught out in the past with last minute projects, I make sure I always have the 3 primary colour paints in the house, so that any colour can be made up. I also keep a pot of black and white for shading.
Then she stuck some kitchen paper in the top which Mark set on fire to create a singed effect.And finally for the lava rocks she stuck some small stones on from the garden.
She managed to do all this without any eruptions or melt-downs of her own!
Not that I'm biased, but I'd give her a gold star for this. Well Done Amy.
