Boil 1 1/2 cups of water in a pot. While the water is boiling, add the jello packet to a mixing bowl.

Add 1/2 tsp of nerds at the bottom of each Jello cup. This will look like rocks under the water.

Once the water is boiling, pour it onto the jello packet contents. Mix until it is dissolved.

Pour the cold water into the hot water and stir for 30 seconds.

Pour the jello into each cup, filling 3/4 full.

Put the cups in the fridge for at least 2 hours.

Remove and make sure that the Jello is set. Put the mermaid tails and mini forks into the cup.
