u no liike how you twist it and the top pops off I cant do it whats the sience behind it air pressure?
Use a thin plastic bottle like Arrowhead water bottle or the new less plastic eco frienly waterbottles by aquafina.. Place the cap on so it is barely on but still holds in the air. Then you grasp the bottle and twist and the cap pops off.
because when you squeeze the bottle you are creating preasure then when u twist the cap all the air is forced out and it causes the cap to pop
but why dose it do that ?!?
