Salt gardens are shallow, man-made pools or basins used to produce salt through the process of evaporation. They are typically found in coastal areas where seawater can be easily collected and channeled into the salt gardens.

Salt gardens have been used for centuries as a method of salt production and are still utilized in some parts of the world today. **

Floating magnets are magnets that are suspended in the air without any visible support. This is achieved through the use of magnetic levitation, where the repelling force between the magnets and an electromagnetic base or another magnet is used to counteract the force of gravity and keep the magnets suspended. Floating magnets are often used for decorative purposes, educational demonstrations, and as a novelty item. They can create the illusion of objects defying gravity and add a unique visual element to a space. **
