Is an empty bottle really empty?

Hindi ko kaia alam bakit u ako tinatanung eh ako nga itong nagtatanung eh!

No mass is either added or taken about by separating a solid, like a water bottle, into separate pieces. All of the smashed pieces' weights add up to equal the weight of the unbroken bottle.

I would say no. You can make it very cold, but it is already an inflexible (for all intents and purposes) solid.

ask your doctor or the local pharmacy

Whatever you want, as long as it can fit in there. Those dang pills are small!
