WE made this dough today and used it to make models from Alice in Wonderland. It is a very soft and nice to work with.
2 cups bicarb of soda (you can order large boxes from Amazon)
1 cup corn flour
1 1/2 cups cold water
Put 2 cups of bicarb of soda, 1 cup of cornflour and 1 1/2 cups of cold water
in a pan. Stir the ingredients until you have a smooth consistency.
Place the pan over the hob over a medium heat. Stir the mixture until it boils.
stirring to remove any lumps and cook until it has the consistency of mashed potatoes. Keep a
close watch on the pan and stir every few minutes to avoid burning the
Allow it to cool. Then sprinkle a little cornflour on a clean kitchen
surface and knead the mixture
until pliable, then use as desired.
Knead in more corn starch, a little
at a time, as needed if the dough is too "wet". Keeping a damp kitchen
towel over the extra dough, it will keep for some time. It could be coloured with food colouring at the cooking stage too!
We have left it on the window to dry and then we will paint our models!
