I was shocked to see a semi professional medium made by Crayola!!  I have used Crayola products all my life and always considered them to be children's art materials.  Not so!!  These are incredible.  You can use them like the old crayons you were used to coloring with as a child, but when you touch them with water...WOW...they look like paint and act like paint.  You have that element of control with the looseness of liquid paint.  Amazing!
