What are other things you can use as a magnifying glass?

You can use a variety of objects as makeshift magnifying glasses, such as a clear water bottle filled with water, which can create a lens effect. A drop of water on a flat surface can also magnify small objects underneath it. Additionally, certain types of clear plastic, like a CD case or a piece of curved glass, can serve as effective substitutes for magnification. Lastly, even a smartphone camera lens can be utilized for magnifying small details when focused correctly.
