Kerryn Palmer - Playdough volcano - 19 August
There are many different recipes for playdough, this is the one I use at home as it keeps for ages in the fridge, also it is lovely when first made as it is nice and warm.
1 cup Flour
1 cup water
1/2 cup salt
2 tsp cream of Tartar
2 tbsp Cooking oil
Mix up and cook over a low heat, stirring as you go to get rid of lumps, add food colouring last, mix and cool.
Playdough is great for exploring texture, experimenting with
material, moulding, manipulating, making, developing hand, eye,
arm, body co-ordination and developing skills with fingers and

Put two Tablespoons of baking soda (approx.) in a small jar with a few drops of red food colouring.
Build up a volcano mound around the jar with playdough (you can also use plasticine, sand, clay)
Leave the top of the jar free.
When volcano is ready, pour 1/2 - 1 cup of white vinegar into the jar and watch the lava flow!
You can keep adding more vinegar until soda is all gone.
This is a great activity done outside with sand or dirt and then you can get really messy!
