Got Goop?

                                  Goop is fun, safe, reusable and although messy, cleans up easily.

1 packet of cornflour (I use a cheap generic brand)
1 – 2  cups water
food colouring, tempura paint powder or acrylic paint (if you like)

Mix water into cornflour a little at a time until you have a gloopy consistency. Drop the colouring in (if using) to the depth of colour you like.
Put into a container or tray and play!

When the children are finished it can be stored in a container with a lid. If it dries out just add more water and stir again.

* A note about food colouring.
The children ended up with coloured hands, if this is undesirable go with the paint options.
