Step 1

Assemble your ingredients.

Step 2

Bring the water to a boil. Measure out one cup and put it in a bowl with the jello powder. Whisk with a small whisk or a fork until the jello is completely dissolved.

Step 3

Add the rum and vodka to the bowl and stir again until it is all mixed.

Step 4

Uncap the syringes and suck 2 ounces of the liquid into them. Depending on what syringes you’ve found, they may have a marker on them to indicate 2 oz. If not, you can always measure a little liquid out, suck it into the syringe, then judge the rest based off of that.

Step 5

Once you’ve sucked the liquid in, squirt a little out like doctors do in tv shows. It makes you feel cool, but it also helps get rid of pesky air bubbles.

Step 6

Cap the filled syringes and put them in the fridge to set. If you can, place the syringes standing up so they don’t leak out of the caps. If you don’t have caps, you’ll definitely want to set them up straight!

Step 7

Leave the jello shot syringes in the fridge for at least 4 hours so they can fully set. If you want, you can leave them at room temperature before serving so the jello will slide out a little bit easier.
