If you need to see any small creature, such as a spider, mosquito or fly, it is very simple.
Put insect in three-liter jar. Tighten the neck top with cling film, but not pull it, but rather selling it so that a small capacity. Now tie a rope or elastic film, and pour water into the recess. You will have a wonderful lens through which you can very well see the smallest details.
