Prepare a batch of instant vanilla pudding, following package directions but reducing the amount of milk by one-half cup.  You can do this with the children if you have time - allowing them to take turns mixing up the pudding and having them see how it gets thicker.   Divide up the pudding into 4 bowls and a different color food coloring to each bowl except for 1 bowl (leave that one a yellow color).

Next, have the children wash their hands. Give each child a piece of waxed paper and a spoonful of each color pudding. Encourage children to use the pudding to fingerpaint on the paper.  Encourage them to watch how colors are mixed and or combined to make new colors. Questions about touch, smell and taste can be asked.  When done, just throw the paper away and wash up!
