In a glass microwaveable measuring cup, bring ¼ cup water to a boil. Then dump in the lemon Jello. Mix until it if fully dissolved. Then add 1 ¼ cup cold water and mix in. Now add ½ cup vodka (add this last as you need to cool it down so the alcohol is not burned out).
Place all of the shot cups on a cookie sheet. Fill all of them half full with the lemon jello mix and place in the fridge. Allow to fully set.
Now make the orange Jello just like you did the lemon. Pour over the already set lemon Jello, filling the shots. Allow to set fully before you top all of them with a spray of whip cream.
Note: These can be easily made without alcohol. Just simply replace the vodka with cold water.
