15 litre/4 gallon water bottles

I have a lot of 15 litre/4 gallon empty, non-refillable water jugs.

I keep searching, but, cannot find ways to use them.
There are so many ways to use 2 litre pop bottles:  making nifty stuff, building green houses etc.
Surely there are creative ways to use these.

Can anybody help with ideas or maybe point me in the right direction?

Seems like a good base for a raft / barge.

Cut the top, find a way to bind them et you have wonderful shelves!

Follow any of the 2 litre bottle projects, and make a larger version!


Have you thought about the recycling bin?
Cutting them into flat lines for repair jobs?
Heating them in a big tube or oven to get smaller but extremely sturdy bottles?
Filling them hydrogen and oxygen for a big boom? ;)
