This Mechanical Fruit Bowl Refuses to Stay One Size

Fruit bowls are probably one of the only kitchen items that can drive you crazy because, let’s face it, they never quite keep up with the amount of fruit you’re attempting to fit into them. Two to three pieces will rattle around the bottom of an empty bowl, while piling in too many will send the entire thing crashing over the rim and onto the countertop.

Simone Giertz eventually solved this problem after four years of experimentation. Her creation, a mechanical bowl that expands and contracts, is stunning. Simply twist the handle and drop in a few of apples without anxiety; the sides will pull in, ensuring that the fruit nestles snuggly together. When you add some tangerines, the bowl stretches outwards to accommodate them.

The ingenious part is concealed in the flat base of the object. An iris mechanism performs the magic. Rods traveling along rails and pins sliding into curved slots accomplish the task. Give the center handle a turn, and every wall section glides outwards in perfect synchronization, leaving no gaps even as the diameter varies from roughly 12cm to 20cm. Smaller fruits stay in place since the base is strong and sealed throughout the process.

However, the early prototypes were a bit of a disaster. Wooden slats were uneven, brass rods left microscopic escape routes open during expansion, and soldering joints continued to break after continuous use. To perfect the design, Simone built dozens of prototypes, cutting, bending, and redesigning components by hand. A breakthrough occurred when the foundation was transformed from a flat disk to a pizza-slice shape, which concealed the raw edges and kept everything in place, and the walls curled into these stunning arches, which brought both strength and balance to the design.

All of these lessons have been incorporated into the most recent brass prototype. The art-deco curves sweep upward from the base, and the solid center brass handle resembles an old-fashioned ice pick, providing a terrific grip for dragging the bowl around as well as a precise way to resize it. Pick it up, and it feels substantial in your hand. Twist the handle, and the sides move with delightful precision.

The wooden prototypes are still kicking around, and they look terrific, all warm and modern, but the brass version, in my opinion, provides a new level of joy. When the mechanism is activated, the metal sings, and light strikes the polished surfaces, highlighting every deliberate angle. Everyone who observed the build was sold on the brass for its clean lines and mechanical honesty.

Next, factory production, or so we hope. Once food-safe coatings are applied and a few small changes are made for dishwasher compatibility, the bowl should be on shelves by 2027. Until then, Simone’s current prototype continues to solve her kitchen difficulties on a daily basis.
