A real build not nickle and dime wannabe junk

I started out with coffee cans and graduated up to a 5 gallon water jug.
Dumped all the cans in and filled it a 1/3.
My goal is to have it full by the time I'm 65. :D
I also save pennies in milk jugs, a gallon jug holds only $60 sum bucks. lol
5 gal. ? you won`t be able to pick it up @ 65. Bust out the hand truck:p
