I held fireworks above my head, and learned to ride a bike.

• I didn't expect to watch a full-length documentary on theme park lines, but Defunctland's history of Disney's FastPass kept me interested all the way through.
   
• A day in the life of a resident in Longyearbyen, the most northern town in the world.
   
• Fran Blanche has been digitising old corporate movies, and this 1982 film from British Telecom about telephone exchanges is an absolute gem. (Brief warning for flickering lights at around 2:45.)
   
• Rob Scallon investigates a musical instrument the size of a building.

• The world's deadliest thing. Brilliant title, well written post, did not expect the answer it gave.
   
• The race to understand "immune amnesia": I had no idea that measles could 'reset' the immune system.
   
• And finally, why paper jams persist is a long and winding article that's worth the read.

Thanks for the kind words about last week's video on the radon spa: it feels rather like I've dodged a bullet with that one, as I haven't had all that many complaints about it. (Apart from a few angry homeopaths, but fortunately the more they complain the less effective they become.)

All the best,
