Where do tubes come from?


OK,

From reading I know that tubes come from military equipment and from organs. Where else do they come from? Old toasters, TV's, ???

Thnx,

PS - Toaster was a joke

When a wave rolls over a reef, it pitches out at a faster rate forming a hollow cylinder. I may be wrong here but I don't see how they could come from Russia. So the correct answer is "sea".
