Supply the arm
The valve feeds water through a rotary union.
Machines & motion
Reaction Spin Cylinder
Feed opposing water outlets and explore the reaction that spins a cross-arm.

3D MODEL
Load the 3D model to rotate and zoom. Approx. 4.1 MB.
Design concept shown in a fixed pose. The 3D view explores the form; effects and mechanisms are illustrative.
FROM ACTION TO DISCOVERY
How the interaction works
Release the jets
Water exits through outlets arranged tangentially at opposite ends.
Observe the spin
The outlets' reaction produces a turning effect around the central axis.
A CLOSER LOOK
Perspective render
Explore the arrangement of a red rotating cross-arm, opposed tangential outlets and a transparent splash cylinder.
LEARNING THROUGH PLAY
What visitors can discover
This concept brings action and reaction, rotation and water jets into a shared water-table setting. Visitors can explore the idea at their own pace and compare what they notice with a partner.
Action and reaction
Expelling water in one direction creates a reaction on the device.
Torque
Outlet arrangement determines how the reaction contributes to rotation.
Observation
The clear surround allows visitors to follow the moving arm.
PART OF A BIGGER WATER TABLE
Planning Reaction Spin Cylinder
Keep the valve accessible and the splash cylinder clear to view. Develop rotary sealing, flow and rotational clearances through prototype testing.
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.
