This drink looks gross if you think of the name while imbibing. Use a hollow swizzle stick to create the effect. Stick the straw into the liquid and place your index finger over the end. To drop it, just take your finger off the end of the straw.
1 1/4 oz. Peppermint Schnapps
1 Drop of Cream
1/2 Drop of Grenadine
Pour Schnapps into a pony or shot glass. Run the drops down a bar straw into the middle of the shot.
