First squeeze out the glue in any design you want.
Then cover the glue with salt - be generous you don't want to skimp on this part!
After that shake off the excess salt into a bowl so that you can use it on the next picture
Next the fun begins!
Dip your paintbrush into some water and then the paint and then put a drop of paint on one spot.
(you don't need to actually brush it on)
Then watch as the paint 'magically' runs along the line of salt!
She loved it!
And liked watching the different colors chase each other.
Tip: instead of liquid water colors,you cold use some water that has been colored with food coloring.
An eye dropper could be substituted for the paintbrush.
