This was great little project to do! We love making our little recycled Crayons and my 6 year old loved building the recycler

This is a very cool idea and activity. I used this activity to support the topic of being resourceful (use the sun and perused crayon that we have) and work toward creating something new, while minimizing waste. My 16 years old daughter incorporated her 6 years old brother in the activity.

We loved this one!!! Easy, but fun to build, the sunglasses are adorable, and it can be used over and over to recycle crayons. The rainbow shaped crayons that popped out were adorable and usable as well.
