We challenge you to plan out the most epic prank this April Fool’s. If you’re running low on ideas, check out the Prankster Skill for more projects like this head in a jar illusion. Using a photo editor, blend two images together to create a flat image of a head, laminate it, and submerge it in a jar. When the flattened image is inserted into the curved jar, the water distorts it - giving it the illusion of a decapitated head in a jar of preserving fluid.
