When I was in London in September, I went to the Notting Hill street festival with some friends. Most of the sidewalk vendors were selling food. But I saw a woman with a balloon in her hand selling laughing gas for 2 pounds a hit! I had to try it. Mehrdad Aref-Adib took this video when I was inhaling. The woman said I had to breath in and out twice to get the full effect. I did get a funny feeling and I thought it was interesting that the gas had a sweet taste.
