Change up the Jello. I use strawberry or watermelon jello so it matches the color of watermelon, but you can totally change up the flavor that you use.

Use a large bowl. It is easiest to make the jello mixture in a large bowl and then pour it into the watermelon bowl.

Add Chocolate Chips. You can add a small handful of mini chocolate chips into the jello before it has set to make it look like there are watermelon seeds in it.
