you wanna try doing it with one finger...that sometimes has a life of its own....a little tip for you...where you can enjoy the best of both worlds....take 50% fat Pepsi and 50% cheap red plonk...pour into a pint glass add some ice cubes...then after 1st pint..try backtracking and editing.....i,ve put myself in the mood for a 50/50 now....but i. don.t have any skinny Pepsi....drat!
