> 1) Does hard alcohol (aka Jack) come in 40oz?
Yes they do. Perhaps not where you live, but I thought they did pretty much
everywhere. I know that they do in Canada and the US.
> 2) how big is a fifth(inches wize)
A fifth is 1/5 of a gallon, also known as 26oz, also known as 750mL. "Fifth"
refers to volume not height, so if its a brand in a tall slim bottle it will
be taller than a shorter & wider bottle of the same volume.
> 3) I thought beer only comes in 40oz while hard alcohol in fifths
I think you've seen "Boyz'N'Tha Hood" too many times. Beer comes in many
sizes from 341mL bottles (haven't you ever seen a beer commercial?), to kegs.
Hard alcohol anywhere from approx 30mL (1oz) to....well, 3 Litres is the
biggest I've ever seen. Sometimes called a "Texas Micky". Normal increments
being, 30mL, 50ml, 375mL(12oz), 750mL(26oz), 1L(35oz), 1.18L(40oz), 1.75L, 3L.
Hope this answers your questions
