I really like how the box can tilt in order to capture the sun at different angles. This not only helps teach about the movement of the Earth throughout the day, but also helps keep the experiment successful in melting the crayons. This has been a big hit. The kids also especially love the hidden Kiwi character in one of the crayon tray slots.

It is cool because you can make different crayon shapes.

By far the best crate we’ve gotten! So very cool you can make your own crayons. Wish it were made of sturdier materials though. That cardboard isn’t going to last all that long.

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.
