2 (6 oz.) pkg. lemon gelatin
4 c. boiling water
1 1/2 c. cold pineapple juice
2 1/2 c. cold water
3 c. washed green grapes

Dissolve the gelatin in the boiling water in a large bowl. Stir 2 minutes. Stir in the pineapple juice and cold water. Refrigerate until the gelatin just begins to thicken, about 1 1/2 hours.

Stir in the grapes. Refrigerate 30 minutes. Stir again to give the "slime" a lumpy appearance. Refrigerate, covered, until ready to serve.

NOTE: Serve the "slime" with hot dogs and "blood" (ketchup).
