Why Switches Click, the Ingenious Soda Can, and a DIY Plywood Side Table
Why do light switches make that clicking sound? Does it serve a purpose? Do people just enjoy that satisfying clack? Or are switches just cheap, so they make noise?
I don’t want to give away the answer. You should watch Alec’s interesting video on his Technology Connections channel on YouTube. As always, he does a great job explaining why this particular piece of technology is designed the way it is.
I watched The Engineer Guy’s video about how an aluminum can is made several years ago, and at the time, I thought it was extremely interesting. It popped up in YouTube’s suggested videos again this week, so I watched it again, and it was just as intriguing to me now as it was the first time!
Why are soda cans cylinders? Why is there a bulge in the bottom of the can? How does the pull tab work? The pull tab is significantly more interesting than I ever would have guessed!
I don’t know anything about furniture or the history of furniture. I’m taking Make It’s word that this side table of his qualifies as being mid-century modern, because I don’t know what that means.
I do know one thing, though: his plywood side table looks awesome!
