Start by gathering everything so you can move quickly once the gelatin is mixed.
Pour the boiling water into a bowl and add the lime gelatin. Stir well until the gelatin is completely dissolved and the mixture looks smooth.
Add the tequila, triple sec, and water. Stir again until everything is fully combined.
Carefully pour the mixture into your shot glasses, filling each one evenly.
Place the shots in the refrigerator and let them chill for about 5 hours, or until fully set. Serve cold and enjoy responsibly.
