Oh and this old vid of 949 6UL wheels being flowformed - fairly well known in the miata/mx5 community  Still good. |

One of my favourite youtubers takes apart a thermos cup.
But the real interesting thing is when he discusses why iron-based alloys more rust vs aluminium and how oxide molecules/layers interact with the base metal structure. An education!

So erm, you can't kill a fruitfly in a microwave, not with direct microwave energy at least.

doesn't get much more random or interesting than quantum physics
i dont pretend to understand it all but it is so weird!

You made me go away and look up the Schneider Trophy. All I knew was the Supermarine S.6B won the trophy outright as the third British winner in a row. Amazing to see how fast the development was. The first winner in 1913 averaged a little over 45mph.  18 years later they were doing 340mph. |

It Kinda did. Macchi produced some rather good but not very well known fighters - all that aero/structure work paid off. infogalactic.com/info/Macchi_C.202 |

Aviation fastener tech is quite different to our automotive stuff.
Take lockwire for example..

A thing I never knew which probably qualifies as both random and interesting: Boeing 747s were designed with a fifth engine station so that an ordinary scheduled flight can transport a spare engine to wherever it's needed: www.airliners.net/photo/Qantas/Boeing-747-438/2760260/LA clever facility that's rarely used because engines are so reliable these days. The one pictured was last year, five years after the previous one. This came up in a discussion of the Air France Airbus whose engine broke up in flight last week. I'm told the A380 can't do this trick. |

Still good.
