Living Cactus - Moving Plant Sculpture

Description

Living Cactus is a mechanical cactus that reacts to water without electronics, batteries, or motors.

When water is poured into the base, the internal float rises and opens the cactus arms through a simple mechanical linkage. As the water slowly evaporates, the water level drops and the arms gradually move back down.

The model works as a visual water-level indicator, a kinetic decoration, and a simple physics experiment.

How It Works

1. Pour water into the base.
2. The internal float rises.
3. The cactus arms open.
4. The water slowly evaporates.
5. The cactus arms gradually lower again.

The movement speed depends on the amount of water, room temperature, humidity, and airflow.
