Plants are sensitive to the buzz produced by bees. The petals, in addition to having the function of attracting pollinators with their bright colors, also serve to capture sound. Zumbal is a buzz player that causes the flowers of a plant (in this case lavender) to generate a higher concentration of sugar in its nectar. It works by pressing a button that turns on the fan inside the speaker, which imitates the sound of bees. At the same time, it generates vibrations that the plant perceives to start generating more sugar and attracting its pollinators.
