Vihaan Chamala, 3, from New York impressed judges from the Record Setter Organisation when he named all 198 countries, dependencies and territories on a world map within just 4 minutes and 42 seconds. The judges honoured the little boy with a world record. It all began when his mother Jayasree Appanapally bought a map and showed Vihaan 8 major countries. She was surprised when the next day he remembered all 8 countries. As time passed he grew more curious about learning more countries, and with his abilities to learn and recall, he mastered the entire world map in just two months. Vihaan is the only child of Dr Raghu Ram Chamala and Jayasree, a clinical physical therapist.
