    Aww… I’ll have to wait until Monday when I have fast net access again. You should see how items like hollow tubes, including those square section tubes, are made – you just have a piece of steel with the right size and shaped hole in it and you heat up the aluminum then ram it through the hole – and it magically comes out the other end with the correct shape (which is often pretty complex – but the simple square is easy to imagine).

    Sheet metal being produced from huge rolls of steel is also pretty impressive – especially when something goes wrong – there’s an instant mess of huge amounts of what looks like a very large ribbon. I wonder if there are any videos posted of such events.

    Whiskey. Tango. Foxtrot.
    Why do they have to waste so much milk?
    Remind me to never buy this crap again.

    @WIll: were you listening to the thing? That’s not milk; it’s water with some small amount of vegetable oil added. It’s a very common coolant in industry. Since everything costs money there’s not much wasted either; >99% of the stuff you see spilling will be collected, filtered, and recycled.
