I bought two 3L bottles of cheap, horrible cider, emptied them into a sink, then cut the bottoms off both, stuck 'em together, and then sprayed 'em silver. The secondary tank was made from a similarly painted bottle of nail polish remover, the yellow was electrical tape, the gauge at the top was an old-timey thermometer, and the stripes were just slightly darker spraypaint.

OP here, thanks a ton mate! You're the man.

No, son. I am the Juan. *dusts off shoulders*
