G'day from Sydney,Australia.
When practicing flair moves with bottles & water, firsty never use more than
90ml in the bottle (3oz). This will mean that centrafugal force will be more
likely to keep the liquid at the bottom of the bottle. Keep the throws fast,
full revolutions - ending in either a pour or an upright position. Alot of
bartender make the mistake of double movements (catching the bottle not in
pouring position but not in upright either) this will jerk the bottle an get
water/ liquor in the airhole.
Also, bear in mind that if the pourer stays dry it is less likely to let
liquid out than with a wet one. I.e. once the pourer has let liquid out once
it will tend to leak more.
