Download the 12 sprites and 31 scripts of "Perpetual Slinky" and open it in Scratch Project Notes
Watch the Perpetual Slinky that never gets tangled! Use the mouse to drag steps around to change the action.
This project is just a simple visual effect. I was thinking about parabolic curves and I decided to make a project to demonstrate how handy they are for making trajectories. So if you want an object to be thrown from one location to another, a parabola is a good curve to use.
Enjoy!

i got it tangled
I have no idea how you made that!?!?!?!?!
It wasn't easy - It took a lot of math :) Thanks for giving it a go.
Wow!!!!!!!!!!!
Oh! Very cool! I never realized how useful this was until I took Algebra! :)
Algebra is powerful stuff :)
This is so awesome
Thanks! Glad you are having fun with it :)
cool I feel like Im really using a slinky!
Doody copied this project and didn't give credit!(link to project)
i didnt even knew what credit didnt mean then!
Wonderful.
I like it, though it isn't really realistic.
even then, if you move the steps, it always goes to where it used to be and then goes right to where it really is.
Of course, you are correct. The rings are not attached to each other and real slinkies don't bounce like that. I did the best I could to realize my vision. I had to make some compromises...as is always the case.
(view all replies)Cool! Confusing but brilliant
slinky!yay! i like slinkeys.
thank you for the help for the formula of finding a curve, i knew it was going to be you who is going to have the awnser
No problem! I hope it works for what you want it for. There is an formula for a circle that passes through 3 points...but I don't have it derived or written down. I would have to do some research. It does exist, though!
thats what i call good code!
This Is So Cool, And By The Way, Thanks For Comeing To LEGO Camp
Thanks! And I had a great time at the LEGO camp...it's always fun to work with enthusiastic people like you guys. One thing I forgot to tell you was to check out the Forums...they have something called Critique Groups which can help you join up with other people with similar interests so you can put helpful comments on each other's projects. Also, you can use the Show and Tell forum to tell other people what you have made, if you want.
(view all replies)wow
This is so cool! Your projects are so amazing!
oopsys I broke it.... I put everything in the same playce...
I froze it!!! muhaha. okay im sane now:)
it glitches when you drag a block the the slinky is on. Interesting project. My slinkies always get tangled. but nit this one.
You can also get it to freeze if you place two blocks exactly on top of each other (division by zero). I tried coding around it but was not successful - oh well!
(view all replies)really fun to watch
(link to project)
cool!
hehe quite fun
i am onlye 3$
awesome! http://scratch.mit.edu/users/nmebfromrs
kewl and it does just the right curve very planned
thats cool
fabulous
(the steps)
I tangled it (if you put them all on top of each other)
Yeah, that will lock it up. It causes division by zero. I tried a couple of fixes on it but so far I have not been successful.
awsome!
cool

That's awesome!
GOOD SCRATHCHERS, I NEED HELP WITH THIS, PLEASE (link to project)
Wow, this game is very cool! Great work!
COOL!
sweet
I like how you applied the concept of porabolas into this project. Nice project and thanks for posting it, it really is getting me thinking!
...omgomgomgomg this is aweesumm
incredible!
woah awesome!
I like how if you move the stps while the slinky's moving it's bounce off of nothing then appear to warp through the steps!
i made a remix look (link to project)
glitch:put all steps on top of each other< music!
Great! It has a very Zen feel to it. I love the touch of the steps reacting to the slinky landing.
Thanks! If you have a fast machine, you might enjoy this remix by Forest (link to project)
Oh, im not a 5 recent friend... :'( Its ok. Anyway, I love this game. Whens your next game coming?? PLEASE REPLY!
Well, it's not a game...it's a paint program and I just posted it about 5 minutes ago!
wow this is cool! It's like a slinky
The steps are like notes on a keyboard ..maybe you could link it somehow with aspects of your recordable piano project..
Yet another fine project. Good job. I am adding it to my Scratch lessons gallery.
Wow, that's really cool! WEll done :D
Very agreable and calm movements. This is a great application of the math knowledge, too.
cool project!!
