Sunscreen, weird picture experiments, and an unimpressed cat.

• Thanks to the many people who sent in Currently Hannah's definitive video on whether Australian sunscreen is stronger than Asian sunscreen. It's really good! Spoilers: it's really difficult to test sunscreen. Hannah actually does real-world tests on her own skin, and she's also really clear about the caveats of those tests. This is worth a watch.
   
• A breakdown by the Wall Street Journal on how those LED wristbands at concerts work. The solutions are far simpler than I'd expected them to be!
   
• The original cast of Marvel's Avengers movie reunited to redub the movie in the Lakota language. Yes, it's a PR video — but it's also remarkable that the Hollywood came back into the voiceover booth to do this, and it's also a brief insight into the process of dubbing.
   
• Processing images through guitar effects pedals is a fascinating combination of analogue and digital experimentation.

• Would you like to buy a model village in Cornwall? (It's only a small model village, and it does come with an entire house attached.)
   
• Type in Morse code by repeatedly slamming your laptop shut.
   
• If you liked last week's daily crossword-clue game Minute Cryptic, and want an easier introduction to the world of British-style cryptic crosswords, then the Guardian's Quiptic is a weekly, web-only puzzle that's a bit more gentle than most.
   

And finally: the world's largest functioning whoopee cushion and a thoroughly unimpressed cat.

All the best,
