In a heavy bottom saucepan over low heat, combine water, sugar and corn syrup. Stir until sugar has melted and mixture has reduced, approximately 5 minutes.

Remove from heat and allow the mixture to cool for 10-15 minutes, but not too long or the mixture will start to harden.

Toss grapes in the simple syrup and then arrange in a single layer on a wire rack. Allow to cool for another 10-15 minutes.

Place gelatin in bowls or plastic bags, separate bags/bowls for different colors. Spoon gelatin over grapes or shake in the bag until fully covered. Tap off excess gelatin.

Place on a parchment lined baking sheet. Allow to set for at least 15 minutes, place in the refrigerator or freeze. Store grapes depending on how you enjoyed them- room temperature, the fridge or the freezer.
