Spirals Ursula Sadiq 11/5 '14

I want to build a spiral lift for balls, that, as it spins, lifts the balls to higher heights, from whence they can roll down a track or tracks of yet to be rube-goldberg inspired loveliness.

How to build the spiral? How to turn it? 

Actually first, what balls? I have pingpongs around. And marbles. (cue the "don't lose your marbles" quip)

Plan A: Pingpong Lift from stacked discs of carboard. I have a kid-free and party-free Friday & Saturday on tap. And lots of amazon shipped boxes.

Still drawing a blank on turn mechanism. I'm sure something will turn up.

Archimedes spiral is always fun and simple, as is the vertical rotating disc with marble-sized holes in it. I love marble ramps, we made a lot of them as kids. For a motor you might want to look into some of the Lego accessories!

I'm not getting the "vertical rotating disc with marble-sized holes in it" reference. (And yes, I spent much time thinking about it while I pretended to watch SuperWhy with my 3yr old). Do you have a picture you can point me to?

This is a pretty good animation.

If you google image/video search for "Marble lift wheel" you can see some other examples.

thanks. that works. I think I'm going with ping pong balls and this sort of lift https://www.youtube.com/watch?v=ULIuuNDptcc But might add that sort of lift wheel for extra effect.

PS: Don't google "Ball Lift" if you are looking for info on this. Unexpected results.
