Peanut Butter and Jelly Illusion

A jar of peanut butter and a jar of jelly are displayed. A black cover is placed over each jar. Like magic the peanut butter and jelly switch places. It's here, no it's here. Back and fourth. Comes with illustrated step-by-step instructions. Compatible with most popular jelly brands off the shelf in your local supermarket. Jelly is not included.
