The crickets did live for a week and my fish lived for more and so 3 days. My predictions came as true as Edward Cayce?s. During this experiment I learned that a tiny environment within a 2 liter bottle was possible and it could very easy be capable of life. It seems in the end this experiment has made me wiser and stronger in a sense and gave me strength to keep on marching toward a bright future in which the old days shall return and everyone shall be just as it once was many years ago?..
