engineering cocktails

Many people think that the engineering types are square and boring, but many-a-times we find ourselves the funniest bunch. (well, maybe boring people don't find themselves boring)

I saw this engineering drawing on making drinks, produced in 1978 with the latest revision made in 2008. Yes, you can find Singapore Sling inside.

Any Professional Engineer wants to check and approve the drawing? Then we can send for fabrication.
