How To Start A Fire With A Condom
Mike Richardson of Primitive Ways shows how you can use a condom, latex balloon, or glove to create a focused lens. Just fill the ballon or condom with water and squeeze into a spherical shape, the more spherical the better according to Mike.
Clear latex balloons, condoms and gloves are opaque untill they stretch. The focal length on these spheres is short, about one to two inches, depending on the size of the balloon.
