Fill the first cup
The valve directs water to the highest open bucket.
Machines & motion
Follow a chain reaction as offset cups fill, tip and pour into the next cup.

Load the 3D model to rotate and zoom. Approx. 1.5 MB.
Design concept shown in a fixed pose. The 3D view explores the form; effects and mechanisms are illustrative.
FROM ACTION TO DISCOVERY
The valve directs water to the highest open bucket.
When the cup tips, its discharge feeds the next stage.
Counterweights return emptied cups while water continues toward the basin.
A CLOSER LOOK
Explore the arrangement of a descending series of offset tipping cups with pivots, counterweights and a supply valve.
LEARNING THROUGH PLAY
This concept brings balance, sequences and gravity into a shared water-table setting. Visitors can explore the idea at their own pace and compare what they notice with a partner.
One stage supplies the material needed for the next.
Accumulating water alters the turning effect at each pivot.
Visitors anticipate which cup will move next.
PART OF A BIGGER WATER TABLE
Align each discharge with the next cup and contain the final splash. Prototype cup balance, reset weights and clearances before fixing the arrangement.
The arrangement can be developed for a museum, science centre or play space as part of a custom water table. Final dimensions, materials and operating performance are established during design and engineering.
