Leeunwenhoek's New Invention
Leeunwenhoek's Last Name isn't the only interesting thing about him...
In efforts to see his thread better, Anton Leeunwenhoek found that by putting the middle of a small rod of soda lime glass in a hot flame, he would be able to pull the hot section apart to create two long threads of glass. Then, by reinserting the end of one whisker into the flame, he could create a very small, high-quality glass sphere. The spheres he created became the lenses of his microscopes, the smallest spheres having the highest magnifications.
