Marble elevators


In a parallel line of development, we are playing around with marbles and chain reaction elements. One of the problems that we're constantly facing is how to work against gravity. It's easy enough for a marble to roll down an incline, but how do you bring it back up? Here are two solutions Walter came up with.

in reaction to this video, overheard on twitter from @coreyfro: @Exploratorium I've always wanted to make a solid state ball bearing conveyor using a slowmo version of a rail gun.

Hey Alex, keep an eye out for that, sounds cool. If he ever actually makes it, we're interested! :)

Such a simple looking solution, yet complicated to make. The craftsmanship that went into making that was very impressive, thanks for sharing!
