You have to have somethng to mix/shake it in - if you don't have one - maybe you could just use an empty jar:)
Cosmopolitan
1 oz Vodka
1/2 oz Triple sec
1/2 oz Rose's sweetened lime juice
1/2 oz Cranberry juice
Lime wedge
Shake liquid ingredients like hell in a shaker with ice. Place lime wedge on the rim of a Martini glass. Pour mix into the glass.
