A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.

Through the exhibits, children are allowed to freely participate in the exhibit games, and the fun of hands-on experience stimulates their strong scientific curiosity, enabling them to understand scientific principles such as Bernoulli's theorem. This allows them to seek, learn, and apply science in the game process, and find solutions to scientific problems.
The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
The Bernoulli principle was first proposed by Daniel Bernoulli in 1726: "In water or air currents, if the velocity is low, the pressure is high; if the velocity is high, the pressure is low." We call it the "Bernoulli principle.
Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.

An Archimedes screw returns balls to the top of the run.

Attach a theme outline, a floor plan, or nothing at all — a photo of the space is enough to start. Quotations are issued against a real exhibit list, not per-square-metre guesses.
