There are different "techniques" of squeezing the sipper.
One of them is the Squeze_2_Crush technique. (**Do not try this at home - It might cause extreme hydration, lens damage and might also require Mass clean-up operations :-D )
1) Take a deep breath and think of the guy who bullied you in school/your Boss
2) Hands on the shutter
3) Exhale with your fists crushing the sipper to deploy Parachutes !!
4) FLAsh fLASh FfASH to capture them all !!
** Results may vary !
