    Streaky vinyl records are the Dum Dums mystery flavor of the music world (opens the original)

    Excerpt · English

    Read excerpt

    One of my favorite newsletters is called Why Is This Interesting? It comes out every day, and they typically interview an interesting person to talk about their media diet or special interest. In today's issue, they spoke to Todd Osborn, a US Air Force weapons systems veteran who is building a flight school. He talked about why vinyl records are usually black. They're black because they are tinted with carbon powder, which makes the plastic tougher and less likely to attract dust because it does

    The Lotus card shuffler fills the gap between $20 junk and $5,000 casino machines (opens the original)

    Excerpt · English

    Read excerpt

    The Lotus is a card-shuffling robot. It bridges the gap between super-cheap card shufflers that don't really work and casino-grade ones that cost thousands of dollars. This one is under $100, and it looks great. From the company's Our Story page: "At the bottom, you have $20 plastic shufflers that jam, break, and sound terrible. At the top, there are casino-grade machines that cost $5,000 to $15,000. In between? Nothing." The company designed it for what it calls the "grandma contingent," people

    A cereal-box whistle that could trick the phone system into free calls (opens the original)

    Excerpt · English

    Read excerpt

    In today's edition of Dan Lewis's excellent Now I Know newsletter, there's a photo of a red plastic whistle that used to come in boxes of Cap'n Crunch cereal in the 1960s. Besides being a cool-looking whistle, it had a unique property that made it popular among phone hackers. It produced a tone at about 2600 Hz that, when played into a payphone, would let you make free long-distance phone calls. A former Air Force engineer named John Draper used the whistle to make free phone calls and was the s

    What is the best paint for painting rocks? (opens the original)

    Excerpt · English

    Read excerpt

    I've painted rocks for years, off and on. It's less intimidating to paint on a rock than on a canvas, and it is easier to display rocks than canvases. You can just set the rock on a desk, table, or any horizontal surface — no mounting hardware or holes in the wall required. Plus, rocks are free!

I still haven't found a perfect paint to u
