Sour Patch Grapes

Place each Jell-o flavor in a gallon-sized resealable plastic bag. Set aside. Remove grapes from stems and rinse in a colander, shaking the colander to remove any excess water (grapes should be damp, not dripping wet). Spritz with lemon juice, tossing the grapes to lightly coat them. Place a handful in each bag, sealing and shaking to coat. Remove from resealable bags, plate and serve.
