How did Louis Pasteur successfully demolish the popular theory of spontaneous generation?
Louis Pasteur used a special swan-necked flask for the experiment. He took a mixture of sugar and yeast powder, filled it in the flask, then boiled it as a steady current of steam rushed out from the S-shaped tube –causing the death of all microorganisms. After this, the flask remained unchanged, however, when the neck of the flask was cut-off, a thick growth of microorganisms was observed which presumed that there are microorganisms that could not reach the flask in the initial stage, however, in the second phase, they came in direct contact with the solution.
