Foam & Fizz with a Color-Changing “Street Trash” Tenafly Viper Cocktail

In the 1987 film Street Trash, a case of expired alcohol from the 1960’s called Tenafly Viper is unleashed upon the vagabond community, causing anyone who drinks it to melt away into a hideous rainbow of goo.

This cocktail starts off with a homemade bright blue Tenafly Viper liquor made with butterfly pea flower, which changes to a bright purple when you add in a squeeze of lime juice! If you want to take it a step further, drop in a fizzing tablet for foaming, color-changing action, reminiscent of the victims in the film.

What To Do

For the Tenafly Viper Liquor


Add butterfly pea powder to liquor of choice. Allow to fully dissolve before using.

For each cocktail


In a glass, add ice and top with Tenafly Viper liquor, Island Punch Pucker and Peach Schnapps. Fill remainder of glass with seltzer or lemon lime soda. Top with a generous squeeze of fresh lime juice and a fizzing tablet* (if using) right before serving—the cocktail will change color from a deep blue to a bright purple!

For the Fizzing Tablets


Want your drink to fizz, foam, and change color much like the victims in the film? Mix together ½ Cup of sweetened instant pink lemonade mix, 1 ½ teaspoons of citric acid, and ¾ teaspoon of baking soda. Using a spray bottle, add a very small amount of water, just until mixture begins to stick together like wet sand. Press firmly into small candy molds, and allow to dry for 12 hours. Gently remove from molds and allow to dry for another 12 hours. To serve, drop one fizzing tablet into each cocktail just before serving.
