SUGGESTED LEAD-IN: For fruit growers, attracting the best prices for their produce is a chancy thing. As with almost everything that's for sale, prices are governed by the laws of supply and demand. In many countries, farmers can hold back produce from market by placing it in cold stores, selling it when there's a scarcity and prices are high. But this technology is not available in many parts of Vietnam and farmers have the option of either sending their fruit to market in times of glut or watching it rot on the ground. One Vietnamese scientist says he has found a solution to this:a liquid that when sprayed onto crops preserves them for months, allowing local farmers to spread their harvest and so get the best prices. VOICE-OVER: Nguyen Van Khai is a physicist, a graduate from Vasava Military Institute. But his fame is as a chemist and he's known throughout Vietnam as "Mr. Ozonic Liquid", after the liquid that he used to prolong the lifespan of more than 61 types of fruit and vegetable. Nguyen Van Khai makes his magic brew in this makeshift laboratory in Hanoi. Though the actual ingredients are not clear, he maintains that it will kill bacteria, fungi, parasites, germs and insects - perfectly safely. The mixture of gas and liquid is mixed with water and either used as a bath or a spray for produce.
