Nepal’s Flag and National Anthem on the edge of the space

On 30th of April, 2014 Kshitij Lohani sent out the Nepal’s Flag & playing Nepal’s National Anthem on the edge of the space.
Using the weather ballon-high altitude concept he was able to send the flag of Nepal in the edge of the space/ very high altitude (80,000 ft above earth surface). When it reached around 70,000 ft, national anthem of Nepal was played through the speaker inside a payload box.
