Bottled water is definitely not a long-term plan.
Reducing the water consumption does not really solve the problem.
Store the rain water is a nice choice, but you cannot drink the rain water directly, it needs to be filtered.

Explanation:
Therefore, a 10x eyepiece used with a 40X objective lens, will produce a magnification of 400X. The naked eye can now view the specimen at a magnification 400 times greater and so microscopic details are revealed. More on objective lenses here. Magnification is the ability to view an object as larger.
White blood cells ( lymphocytes is correct though)
