    Man I love this show, as a kid and still now.
    They had no problem with telling kids to go to the stove and heat up a skewer with fire.
    These days car batteries have a warning sticker on them stating not to drink the contents.

    Every time Rob or Deane says "sand," I am reminding of Australia's singing sand.

    Rob, you just taught me what a harmonograph was and now I’m endlessly producing art in this style. Thanks, mate!

    That's pretty cool. I've never considered a double-pendulum like that. I won't be drawing with sand, but it does open up new idea possibilities. And I guess that's part of what the show was all about.

      You can use a simple graphing utility. The parametric curves produced are of the form x=sin(at+b) y=(ct+d). Adjust a,b,c,&d to obtain different curves. Graph (x,y) along a range of t.

    I built one of these and used goat‘s blood instead of sand. It created a pentagram design. What should I do now?

    $20 notes no longer have those patterns, since the paper note was replaced by the polymer one

    Don't forget, though, a free pendulum will stay in one place as the Earth revolves and there will be a pattern it will just take 24 hours.

      @@James-kv6kb Exactly, I've watched this show as a child 30 years ago, I didn't set the house on fire, probably because I had parents that made it very clear that using something like a stove by myself is dangerous, nobody should expect TV shows to do the parents job of educating their kids.

      So you believe they "probably" are NOT "properly called" that? Maybe it's worth your time to verify what you want to say before you offer it to countless people to spend much more total time reading.
