i want to know how i can get passed blocked websites. for example, at school, facebook, twitter and all those other sites are blocked. i dont want to hack the principles' or administrators' account.

this is a really awesome channel too
all of this works and they tell the honest truth
i do the IP address at my school ALL the time.. but like it says in the video it might not work at every computer

proxy sites like hidemyass will help.
