These test tubes are actually the blanks or preforms used to make soda and water bottles. The preforms are typically injection-molded from the raw plastic pellets at a plastic products manufacturer and then shipped to large soda and water bottling plants. The bottling plant uses a blow molding machine to heat the preform and "blow" it into the shape of the finished bottle using compressed air. The finished bottle is then leak tested, filled with soda or water, and capped.
