In a medium bowl or large (4-cup) measuring cup with a spout, whisk together the strawberry jello mix and 1 cup of boiling water until the jello is fully dissolved.
Once the jello is fully dissolved, stir in the cold water, lemon vodka, and Triple Sec. Mix until combined.
Carefully pour the mixture between small plastic shot cups. Fill just under the top, so they don’t spill.
Transfer jello shots to the refrigerator and chill for 4 hours until set.
Just before serving, top each jello shot with a gummy fruit slice.
