  1. CW: Lewd, wheelchair

    Follow me here; sometimes wheelchair users might have difficulties with their clothing options to show off their assets, but, what if the chair could do more than merely assist with mobility?

    I present to you:

    The Assless Wheelchair. Like assless chaps, but built into the chair.

    I know, incredible innovation. I just need several million dollars to make this invention a totally real reality.

  3. 🌈 TIL: Color #tv had to solve one stubborn problem.

    Millions of black-and-white sets were already in American homes, so #RCA had to encode #color signals that rode invisibly inside existing broadcasts and only color receivers could decode. That backward-compatible #breakthrough, coming after John Logie Baird’s fragile 1928 mechanical system, finally made color TV possible.

  5. 💁🏻‍♀️ TIL: 🎒🏞️ The Smithsonian traces backpack #design from a two-million-year-old practice to Ötzi’s hazel-and-board frame around 3300 BCE, then follows improvements through a #CivilWar cavalry officer’s patented canvas-and-metal pack, a #Duluth #canoe-hauling design, #aluminum-frame #mountaineering models, and the nylon #JanSport that made the #backpack a school staple. Roughly 450 million are sold annually.

  6. 💁🏻‍♀️ TIL: 🎧☎️ The first headphones weren’t for #music – they were a 4.5 kg (10 lb) harness invented in 1881 by Ezra Gilliland so telephone switchboard operators could take calls hands-free.

    Over 80 years, inventors slimmed them down: the first earbuds with rubber tips (1891), Baldwin’s headband #design (1910), Beyerdynamic’s dynamic headphones (1937), and Koss’s 1958 system that brought headphone listening to the public.
