How to Make Scratch n Sniff Stickers with Jello

1. Decide on the images and associated scents that you want to use. Images of strawberry can be used for strawberry-scented stickers; pictures of lemons can be crafted into lemon-scented stickers. Go through coloring books, comics, kid's books, newspapers, magazines and other printed material.
    
2. Choose and purchase gelatin in the flavor associated with the image and scent that you decide to use for your stickers. Purchase an unsweetened drink mix in the same flavor as the gelatin.
   
   
3. Dissolve some gelatin in a cup water, following the instructions on the package. Use a paint brush to apply the gelatin and water solution to the back of the images that you selected to use.
   
4. Place them in a well-ventilated area to allow the solution time to soak in to the paper and to dry. As it dries, the gelatin will stiffen the paper, and give it the texture for use as stickers. Allow the stickers to completely dry.
   
   
5. Follow the instructions on the package of unsweetened drink mix to prepare a cup of the drink. Use a clean paint brush to apply a small amount of the prepared drink to the front surface of the sticker. Place it once again in a well-ventilated area to dry completely. Once dry, the stickers are now ready to use.
   
   
6. Use your scratch-n-sniff stickers. Apply a little water to the back of each sticker with a clean paint brush, and place your sticker on a surface of your choice. The gelatin solution will serve as the adhesive that will stick it to the intended surface. Lightly scratch the front surface of the sticker to release the scent, and sniff.
