Crayons - from old to new

All kids must have a box of old, broken crayons which they don't want to use anymore, because they look so ugly. We had a very BIG box of such crayon pieces and I kept thinking what I should do with them. I read on Internet that it's easy to make new crayons out of the old ones, but I've never tried that because my kids hardly ever use crayons for drawing.
But now ... with a 3-year-old around the crayons started making a come back and it was time to do something with that BIG box.
This is what I have done:

The process starts in the top left corner.

• Choose crayons of different shades of one color.
• Peel the leftover paper wrapper.
• Break the crayons into small pieces of about the same size.
• Place the pieces in a pot and wait until they melt stirring occasionally.
• When all the crayons melt pour the hot liquid into the mold (be very careful as the liquid will be very hot!)
• Wait until the new crayons cool down and harden.
• Carefully take the new crayons out of the mold.

Many "recipes" on the Internet talk about placing the crayon pieces in the mold first and then putting the mold into the oven, I was not sure whether  the molds I have can be placed in oven so I melted the crayons in the old pot first.
You can make crayons of different shapes or mixed colored ones.

Have fun with new crayons!
