<span style="letter-spacing: 0.0px">&nbsp; &nbsp;Through his varied interests, he has taken part in many competitions and , “hackathons” and research, a notable accomplishment being that he recently completed interesting research on water and food purity. This research study involved water samples and liquified food samples that were placed into an ultrasonic interferometer (, an instrument that measures the velocity of sound in a given substance) after which calculations were done to determine . Generally, the purity. The higher the velocity , the more the impuritiesin the sample. Different tables with graphs in both 2 dimensions and 3 dimensions were made to interpret this data. The usefulness of this This research being that can be used in determining food adulteration and water purity can be easily measured just through a sound simple near-harmless ultrasound wave. This could potentially affect consumer choice </span><span style="letter-spacing: 0px;">As an example to see the use of the research, Mangoes and Papayas in India are increasingly adulterated with Calcium Carbide, a known carcinogen. Another frightening example is that sixty percent of milk, a common commodity that is considered essential to the growth of children, is adulterated in India. Thus, the motivation for the research is clearly seen, to give consumers a method to easily choose between commodities, improve the safety along with having of consumers, and attempt to cause major environmental impacts.&nbsp;</span>
