my cousin tried to teach me when i was about 7, and it took me ages. she started off (she was 8) by stretching bubblegum over the outside of my mouth and telling me to blow. and then attempting to explain it 'just stretch it with your tongue, and hold it with your gums/teeth!'
errr, i don't get it. anyway, it took me a while, and now i can.

jesus i'm bored. when's xmas? argh
