giant alice in wonderland drink me bottle help

[sonicfreak04]

Hi, I know giant prop bottles have been made in the past but the ones I find online are opaque instead of transparent, I was wondering if anyone can give me ideas on how to make a giant transparent alice in wonderland bottle?

It could be made with thin sheets of polycarbonate or PETG
4x8 sheets can be found at Lowe's and Home Depot.
