02 - 1 packet unflavored gelatin (0.25 oz / 7 g)
03 - 1 cup boiling tonic water (240 ml, provides glow effect)
04 - 1/2 cup heavy whipping cream (120 ml)

# Preparation steps:

03 - Add heavy whipping cream, green food coloring, and vanilla extract to the dissolved gelatin. Blend until the mixture is smooth and evenly colored.
04 - Bundle plastic straws together with the bendable ends facing down and pack tightly into a tall glass or container so they stand upright.

06 - Refrigerate the filled straws for a minimum of 4 hours, allowing the gelatin to set completely.
07 - Remove straws from the container; hold each straw under warm water for a few seconds, then squeeze or roll with a small rolling pin to extract the worm shape.
