A standard element: the geometry and the finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and the way it mounts to the basin can be adapted without a new design cycle.
A clear acrylic column on a pedestal. A button starts a pump that draws water out of the bottom off-centre, and a funnel-shaped vortex forms from the surface down.
Water leaving through an off-centre outlet acquires angular momentum, and the free surface drops where the velocity is highest. The vortex deepens until air reaches the outlet, at which point it collapses and starts again — the cycle is the exhibit.
Press and wait, then press again to catch the moment the vortex touches bottom. Children time each other on it.
A standing-height single unit, at home on the dry side or on a shallow plinth in the basin. No splash, so it can sit next to exhibits that must stay dry.
Other elements from the same group. All held to the same specification, the same material palette and the same control package.

A spiral of trays that carries one stream of water down in steps.

A long shallow table where visitors build the channel themselves.

A clear tube you crouch through while water pours down its inside.

Water carries balls up a stair of troughs; gravity brings them back.
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.
