2 cups of baking soda
1 cup of corn starch
1 & 1/2 cups of cold water
Mix the ingredients together in a large pot.
Cook over medium-high heat, stirring almost constantly. The mixture will begin to bubble. Then it will start to clump together.
It doesn't take long at all for the clay to form. Keep stirring until you have a consistency similar to mashed potatoes.
Transfer the clay to a bowl and cover it with a damp dish towel until cool.
Once cool knead the clay until it is smooth. Our clay was not damp, but if yours is you can add a little corn starch to your clay and mix it in.
After a bit of kneading you will be left with the perfect play clay!
Give kids play dough tools, cookie cutters, and other gadgets, and they will surely have a blast!
You can colour the clay with food colouring.
CORAL REEF AQUARIUM
You will need:
Pink card (or foam)
Blue thread or wool
Paint the inside of the cardboard box blue and leave to dry. Meanwhile draw or print out some fish onto the white card and colour in. Remember that coral reef fish are very bright and colourful!
Cut some short lengths of wool and tape one end to the back of each fish and the other end to the top of the box.
To make the coral, cut some tree-like shapes from pink card. See the photo above for guidance on the shapes. Fold over the bottom to create a stand-up base and glue to the bottom of the box.
If you have any seashells use these to decorate the bottom of your box.
Encourage your grandchildren to find out more about coral reefs, especially the Great Barrier Reef, on the internet or in books.
