How to make fire using a condom

Trojan1Fill it with water and squeeze it into a circular shape and use as a magnifying glass…sort of.

The more sphericle, the better the lens works. If the condom is too big, it becomes a squashed sphere and it's focal point becomes distorted, like a line instead of a tight circle. Sometimes just giving the condom a squeeze in the right axis will bring the light back to a nice tight circle.
