I'm pretty sure not every Pakistani is as ignorant as the mafia @ defence.pk thinks we are.
What you see in video is
100% fake zamzam, good job.
No pilgrim is allowed to carry drums of ZamZam and take them out of Haram.
What pilgrims bring home is from certified source, in sealed and stamped bottles, which are checked at airport and than allowed to carry on.
In past govt. was lenient on exports of zamzam but than various govts. of world complain of contaminated water being sold as zamzam.
Now a days, various Islamic /non-Islamic states are on board and they don't allow any water which is not certified by Saudi govt. e.g. UAE, Malaysia, UK, Pakistan, etc.
Still one has to be careful, because there are criminals who paste fake labels on ordinary water, usually unhealthy to drink.
You may find all this info. on web.

Last but not least, what Quran says about lairs can also be googled.
Those who propagate lies to hurt Islam by calling others kafir, khawarjis and nonMuslims are friends and allies of evil.
