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.
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.
But if you are lucky to find and old banknotes in you great-grandmas old mattress you still can exchange them to plastic banknotes in most of commercial banks, however they will take tome to send them to reserve bank to confirm validity.
@@E_y_a_l well said. lack of parental guidance has got nothing to do with the producers of this show . Unfortunately if you treat kids like idiots they will behave like that treat them like intelligent human beings and show some guidance and there's no problems
@@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.

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!
My pleasure - Rob

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

Amazing 👏
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.
Try it on your friends.
Cool 👍
Terrific! Very interesting.
Try it on your sandy friends.
Ye gods I love these clips
Super interesting!
Try it on all your swinging friends! Ummm on second thought...
What if you use ketchup and mayo?
Just heat it up on the stove, and it will melt its way through. What a time.
Still works with most plastics today.
@@timharig I meant the safety aspect of telling a child to do that
@@MushookieMan If a child that is too young to do this have access to a sharp metal object and a stove then it's their parents fault, not the show.

Absolutely love that close up view of Rob's Immaculate Goatee on the upper left 😘
İ think these are more properly called lessigeux figures. Probably butchered his name. Some frenchy.

@@smadaf not sure what you are trying to say. Lisigeux might be his name. Will have to google.
@@smadaf lissajous is the proper name. Some french fkkr. İ can never spell properly SPK whp diego names like that. Sry.

Lissajous are parametric curves of the form:
x = sin(at + c),
y = sin(bt + d)
