The lens is in a concave shape, so it is zooming out the flower, making it look smaller

Similar to the previous one, zooming out the plants and making them look smaller

Here I am testing the focal length of the lens with different volumes of water add to it.

In this photo, the lens is in a convex shape. Here it is zooming in and enlarging the plants, but my phone just couldnt focus properly. Also, the previous lenses kept leaking water. So,I added a yellow teflon tape around the edges to stop the leakage.

The phone liquid lens design involves a compact optical element designed to fit within the width of a smartphone, with light entering from left to right. The Phone liquid lens is formed using multiple immiscible liquids of different densities, each with its own refractive index. Their density difference helps maintain a stable liquid-liquid interface. The aperture radius is small, ensuring that gravitational effects do not distort the interface. Integrated actuators (at micro-scale) vary the internal pressure of the liquid system (through the actuator space in the image), changing the curvature of the interface. By placing several such interfaces in sequence, a complete optical system can be made and by adjusting the curvature of the interfaces a broad focal length range can be obtained. Basically, the entire zoom range could be from 0.5x-20x or much more.
