The Magic Scent line of crayons is one of my favorites from Crayola. It was one of the first boxes I ever owned. I still have my original box from my childhood. The magic scent line came out in 1993. The 1993 boxes featured outdoor smells and food smells. In 1994 probably due to backlash from parents whose kids ate the crayons they changed the scents to non food items. I personally like the food ones better. They just smell better. I have also found most of the boxes on eBay. I love all the different scents in the boxes, especially Fresh Air. All the boxes are slightly different. The 1993 box has a strawberry and grape on the front, the 1994 16 count box has a rose and a pine tree on the front, and the 8 count box has a strawberry and grape on the front of the box.
How do they work? The
US Patent 5039243, fragrance releasing crayons explains it very well. The patent says there are microcapsules on surface of the crayons, and when they the crayon is used to color the microcapsules break and the smell is produced.
