Crayons

To make rainbow colored crayons try partially melting all the colors in your boxes that are broken and not used any more. Try not to stir the crayon mixture too much or you won't get the striped texture you desire. Spray a muffin pan with a non-stick type of spray. Then pour the partially melted crayon mixture into the tins to about 1/4 inch from the top of each one. Be careful because the crayon mixture and the tins will become scalding hot! Set the muffin tins on cake pan racks to protect counter tops from the extreme heat. Doing this will also allow the liquid crayon mixture to cool quicker.
Let the mixture set up for at least three hours, or until they feel totally cool to the touch on the bottom of the pan. Pop them out of the muffin tins. Wash the crayons with warm (not hot) soapy water quickly to wash off the non-stick spray. Dry them with paper towels! Don't use your good kitchen towels or some of the colors of the crayon may ruin them. Lay them aside for a while to finish drying. Use these special crayons for drawing on large paper/posters or to make eye-catching large letters.
