You'll need:

blue jello
gummy fish
clear plastic cups

Let's start:

Prepare the jello according to the instructions on the box.
Divide the jello up amongst the plastic cups you have.
Allow the jello to cool in the refrigerator for about 1 hour.
Place the gummy fishes into each cup and place the jello back into the refrigerator to allow them to set completely.
