I have stumbled upon “Start to Finish” series of books while looking for something on Amazon. We already had a batch of broken crayons that I was collecting for the “melting experiment”, so I thought that From Wax to Crayon book will be a good companion for this activity. First I asked Anna to predict what will happen if we put crayons in the oven. She predicted that they will burn, we will have to call the fire department and papa will not be happy. Then I had her peel and break the crayons into pieces – her favorite part of experiment. Unfortunately, I really messed up on the setup – I didn’t think that crayons will liquefy so completely and so quickly. Putting them into the cookie cutters was not a good idea. We ended up with a big colorful puddle that spread all over foil and eventually cooled into thin and fragile crayon strips. Still, Anna was thrilled with this experiment and happy to try her new “crayon strips”. We will definitely repeat this experiment using molds. As for the book, it was somewhat disappointing. Quality of the photos could have been better, and sometimes the text didn’t quite match the picture. Still, Anna studied it with great interest and added “crayon making” to her list of future careers. She said that she might invent a new crayon and then she will send me the box. So nice of her :)
