In a shaker tin, muddle the watermelon chunks with lime juice to extract their flavors.

Add vodka to the shaker tin.

Fill the shaker with ice cubes and shake well.

Strain the mixture into a pure copper mug filled with ice cubes.

Pour ginger beer over the vodka mixture until the mug is full.

Garnish with a sprig of mint and a watermelon slice for an extra touch of freshness.

Serve immediately and enjoy the vibrant pink hue and refreshing taste of this summertime Watermelon Mule.

Cheers!
