You Will Need

  • Water (boiled and cold)

Other Supplies Needed

  • Measuring cup
  • Watermelon slicer, spoon, or ice cream scoop

  • Paper towels
  • Large knife
  • Leveled space in your refrigerator (it’s a good idea to clear a space in advance:)

Directions

  1. Slice the mini seedless watermelon in half.
  2. Remove the watermelon from the inside! It’s a great idea to get one of these watermelon slicers! You don’t have to throw away the watermelon. Enjoy it as usual:)
  3. Using paper towels, dry off the inside of each watermelon half.
  4. Prepare the two boxes of Jello mix according to the directions on the box in a large mixing bowl (you’ll need 4 cups of boiling water and 4 cups of cold water).
  5. Pour the bowl of prepared Jello mixture into the hollowed out watermelon halves.
  6. Put the jello filled watermelon halves in the refrigerator. Place some paper towels underneath them just in case you spill any (I usually do!).
  7. Let the Jello filled watermelon sit in the refrigerator for 6 hours or until it is completely firm.
