Salad Sunrise Carafe by Arnout Visser

Salad Sunrise Carafe, 2008

Instead of juggling two bottles, just pour oil and vinegar one after the other as the physics keeps them separate. Since oil naturally floats on vinegar, this design puts science on display — the natural separation of the two liquids, eliminating the need for a physical barrier.

The Salad Sunrise Carafe is part of the Museum Boijmans Van Beuningen collection, Rotterdam.
