S4 Stair Mechanism - Build it. Play it. Display it

Unleash your creativity with the S4 Stair Mechanism - a captivating DIY kinetic art marble machine kit! This kit invites you to craft a fascinating staircase mechanism, where marbles roll up and down in a hypnotic flow. Crafted with precision-cut parts, it’s designed for a rewarding hands-on assembly experience with endless possibilities. Here’s what makes it exceptional:

How it works

The S4 Stair Mechanism is composed of Two main parts

• Part 1, the S4 Base Machine
• Part 2, consisting of four Marble Run Modules. See the specific illustration below for details

The Marble Run Modules come in a total of 9 unique designs for you to choose from, as illustrated below

These modules are interchangeable, allowing you to swap their positions with one another. This flexibility enables countless setup variations simply by rearranging the modules. For example, if you select the S4 Base Machine with Modules 1, 2, 3, and 4, you can swap Module 1 with Module 2, or Module 3 with Module 4, and so on. See the illustration below for details.

Typically, selecting any four modules is sufficient for a fully functional setup. For instance, combining the S4 Base Machine with Modules 1, 2, 3, 4 or Modules 6, 7, 8, 9 works perfectly. However, you can opt for more or even all 9 modules if desired. The illustrations below showcase two standard options: S4 with Modules 1, 2, 3, 4 and S4 with Modules 6, 7, 8, 9.
