Fully prepare lime jello per package instructions. Use a fork to break jello apart into small pieces (small enough to fit through a straw) then add crushed jello to a large pitcher of your choice (should be at least 1 liter or larger).
Add pineapple juice and infused vodka to pitcher, then stir.
When ready to serve, add Sprite until the pitcher is full. For best results, pour lemon-lime soda from a higher distance than you normally would so that there’s extra fizz on top of the drink. Serve immediately.
