I missed out on things like this as a kid. At school and home. However I am now disabled and have to rest a lot and I have all the time in the world to enjoy stuff like this! And it makes me feel a childlike fascination. It all came out in the wash in the end... 😀
You know what I want to see now? A millipede! With loads of legs all working... These walker's really appeal to me! I'm going to make some for my dogs and have them deliver a treat. This is just the right sort of movement to excite a dog into thinking it might be alive...
Bruce, you have once again brought out the kid in me. I love science concepts that are easy to create with materials from around the house. Thanks for bringing our family a smile tonight!
it's a 1978 Pontiac Grand Safari wagon, I didn't think a video would fit into my channel but send me an email and I will forward pictures or video of it Bgoknee@comcast .net
For smoother ramp surfaces, maybe some PVA glue 'soles' on the bottom of the legs might give the traction you might want and the ability to walk on a number of surfaces - smooth or rough.
Yo 1:54 - 1:59 I could hear being sampled and looped as a sick beat! Better yet go full acoustic analog and just keep returning them critters to the top at the right time to sync. Groovy stuff! ☮️❤️🎵🌍🤗
Thank you so much for this. there are many videos out there of walking ghost ladders and i keep trying to explain to people how it works and that its just physics and objects in motion. they keep thinking its ghosts X_x
Thanks for another great video. With the spider walker, could thin string be used to connect a walking leg to the diagonally opposite bent down decorative leg such that they would all move in a spider like fashion?
that might be possible, I haven't tried it, I had an idea of attaching the spare legs on thin flexible wire that bounce a bit as it walks but didn't try it. I hope to see others take this general idea and get more creative with it
Hi! At 4:51 i nnoticed that there is some glue on the ramp walkers leg. Could you please tell me why u applied the glue? And does it affect the walker's walking? Please reply asap i need this for a project!
yes these pieces have gotten a lot of use and kids have bent the legs so much that the joint was a bit too loose, if I tried to stand it up it would just fall over. A small spot of glue was able to stiffen it up enough. if making new ones you shouldn't need it
One of the walkers appears to be limping as if it hurt its foot. Maybe that happens if the two front legs aren’t cut or bent exactly the same? I’m not saying that’s bad, it actually makes them look a little more realistic.
Hi Robert, while cardboard is easy to cut and work with, it is also easy to make the cardboard too flimsy or it breaks down through use. A little bit of hot glue can help restore it's integrity.
Does the angle of the curve matter? Did you use a parabola, a brachistocrone, or a catenary curve? How would using such curves affect the Walker's effectiveness? And could you stabilize the front and back legs together (right to right and left to left) to make At-Ats?
Assuming smoothly varying curves, the ratio of the average radius of curvature relative to the length of the legs is more important than the exact mathematical model. Experimentation is warranted.
A small amount of curve, nothing was measured, just an estimate as shown on the video. Higher side of curve is on the inside edge. Working with flimsy cardboard as a building material cutting with scissors does not allow for very much precision. Just make sure legs are all the same length
Maybe a tensegrity walker would make for a curious effect or perhaps employ the rocking motion to actuate a hinged tongue or googly eyes if it had enough sway. A spider with many eyes or something ...
I like that idea, I had thought of making a new spider with the non functioning leg on springy wire so that they would bounce as it walked but didn't try it yet. I keep getting sidetracked
I think this is a great activity for students to try for themselves, do some testing and then use their creativity to come up with more ideas, good luck with it
bruce the concept behing this is actually the reason how wlater lewin sir is able to draw those dottet lines. i was thinking about it. if you see how he used the friction to draw dottet lines is the same concept that help these animals to walk like that.
@@YeanyScience haha so good i was able to relate stuff comeon man he is not the only one me my friends and my phy teachers always compared you to walter lewin sir you are no way less than him in any way. any one who love physics is awsome. i indeed love the simple yet interesting approach pf physics in yoour videos. you are indeed awsome
@@YeanyScience I feel like taking a bite out of every piece, then re-triangulating them, could be a great way to sneak a slice out of a pizza with nobody noticing...
I think these are nice. But are these your original? I have ever seen similar demo that was made by Mr.Noro in Japan. What do you think about this situation?
I see the connection, Interestingly enough I didn't consider this to be as escapement mechanism and yet that is the project that I am currently working on and will probably publish next
@@YeanyScience 1) it oscillates 2)it releases energy slowly. If you had a slope long enough you could run a clock on the back of the cardboard figures by hooking the hands of the clock to the feet of the animals
Prof. Yeany, Thank goodness for channels like yours and Curiosity Show. Please keep these great videos coming!

Desde Uruguay. Con mi nieto de 5 años ya hemos realizado varias de tus maravillosas propuestas.¡Muchas gracias, Bruce! Saludos.
Me alegra saber que estas ideas se utilizan, gracias por escribir
Good to see you again and cool build
Nice and wholesome little physics toy. Thx for uploading
These animals are hillarious because their movements are so realistic, and all without any electronics nor motors. Smart. Amazing.
Bruce, you have once again brought out the kid in me. I love science concepts that are easy to create with materials from around the house. Thanks for bringing our family a smile tonight!
Thanks for the entertaining video Sir; and while not you’re usual fare, I’d love to see a walk-around of that station wagon of yours!
it's a 1978 Pontiac Grand Safari wagon, I didn't think a video would fit into my channel but send me an email and I will forward pictures or video of it Bgoknee@comcast .net
I would literally spend my entire day watching these walk down a ramp :3
You are a true artist sir , hats off to you
Perfect. Can see world domination by cardboard walkers anytime soon.
You are the best teacher ever... I'm your biggest fan
Fantastic experiments we can all try. Really enjoy your vids Bruce. Never to young to learn are we? Best wishes from England 👍
Thanks 👍
This channel is underrated
An A for Science wasn't good enough, you had to go for the A in creativity too. Well, you get them both! Congratulations.
thanks, I hope to see others take the idea and go further than I did
For smoother ramp surfaces, maybe some PVA glue 'soles' on the bottom of the legs might give the traction you might want and the ability to walk on a number of surfaces - smooth or rough.
Or you could cut small pieces of a bicycle tyre and glue them on the feet. This way the animals would have rubber soles, like we humans have. Haha.

Fantastic 👏👏👏👏👏
I love this idea so much!
Wow very nice demo
I love it so much, when I have time i will surely make it 🤩💛
We love all you’re videos
Many nice Bruce!! :D
1:11 that Shane Dawson pizza though
Came here to know science and have fun. Instead of - I'm hungry after seeing a pizza
your video actually ended up at the german young physicists tournament :)
thank you for letting me know, I love to hear that they are getting used
Thank you so much for this. there are many videos out there of walking ghost ladders and i keep trying to explain to people how it works and that its just physics and objects in motion. they keep thinking its ghosts X_x
Hi Juan, same movement, I just went out and tried it with my step ladder, but no luck
Nice
Hello I like your ideas so I am going to make a.i Walker challenge order a.i
It's really cool!
you should make an open competition for this 😂👍👍
Very good
Very cute
brilliant
Thanks, your ide this is very nice for my sun

Muchas gracias.
Hehehe nice 😊
Very funny. Thanks teacher. You're better.
Supper!
My little boy is CONSTANTLY finding reasons to cut up cardboard for his creations. This will be great to do with hi !
life changing

@@YeanyScience ohh ok
Hey Bruce, what physics concepts can go well with this phenomenon?
Marcus Evangelista you have, concepts of friction, angle of repose, objects in motion, and just fun!
cool
☺️☑️✨
One of the walkers appears to be limping as if it hurt its foot. Maybe that happens if the two front legs aren’t cut or bent exactly the same? I’m not saying that’s bad, it actually makes them look a little more realistic.
my favorite walker is the very thin cardboard walker shown in the opening sequence, it seems to dance down the ramp rather than walk.
Would it still work with a bit of hot glue on the inside of their cardboard joint to make it a bit stiffer?
Hi Robert, while cardboard is easy to cut and work with, it is also easy to make the cardboard too flimsy or it breaks down through use. A little bit of hot glue can help restore it's integrity.

Why don't you experiment for yourself? Learning is fun!

너무 귀여워요ㅠㅠ
Time to call the bookie and lay some bets.
😊
I am going to use this for a gravity lesson and then toss in the some of Newton's Laws as well.
I think this is a great activity for students to try for themselves, do some testing and then use their creativity to come up with more ideas, good luck with it
The motion (and mode of movement) of these cute little critters is called "podiating."
thanks Li Li, I hadn't heard that before
bruce the concept behing this is actually the reason how wlater lewin sir is able to draw those dottet lines.
i was thinking about it.
if you see how he used the friction to draw dottet lines is the same concept that help these animals to walk like that.
your right, same idea, I've seen his videos, he was a master educator.
@@YeanyScience haha so good i was able to relate stuff
comeon man he is not the only one
me my friends and my phy teachers always compared you to walter lewin sir
you are no way less than him in any way.
any one who love physics is awsome.
i indeed love the simple yet interesting approach pf physics in yoour videos.
you are indeed awsome
Where can we send our pictures of projects we learned from you? My Five-year-old is your biggest fan! Everyone he meets hears about you!
I would love to hear and see what your son has been up to, my email address is Bgoknee@comcast.net
First
Hey Bruce, pass the pizza.
that spider walking on four legs is horrifying...
funny, my wife said the same thing
Good to see you are enjoying yourself in retirement. (❁´◡`❁)
I am!
1:13 Why is one slice of pizza is noticably smaller than the rest?🤔
LOL, it had a bite out of it
@@YeanyScience I feel like taking a bite out of every piece, then re-triangulating them, could be a great way to sneak a slice out of a pizza with nobody noticing...

why r ur walkers walking but mine rnt
The animals in order:
Tortoise
Spider
AaaAAAaaaa?!?!?!?
Lizard
Llama
thats what I was thinking XD i thought that was funny
this is an escapment mecanism : en.wikipedia.org/wiki/Escapement
I see the connection, Interestingly enough I didn't consider this to be as escapement mechanism and yet that is the project that I am currently working on and will probably publish next
@@YeanyScience 1) it oscillates 2)it releases energy slowly. If you had a slope long enough you could run a clock on the back of the cardboard figures by hooking the hands of the clock to the feet of the animals
who said that the tortoise walks slowly
Anything with a spider moving real or not gets me felling scared
They don't work for me
hello como estas yo saber poquito español
@Lorenzo Perrone AHHHHHHHHHHHHHHH
HELP MEEEEE
No dislikes plzzz...
NO HABLO TACATACA :(
Boston dynamics but cheaper
Do you think he can walk some pizza over here to North Carolina 😂
Hi
