Try this unblocker!

It's new and nobody knows about it yet:

It looks like a lot of school administrator type people have been watching our sources, and are blocking new unblockers pretty much as soon as they're released. So all the unblockers we've posted on this site are probably blocked and any new ones we post from that same source will be blocked very quickly as well. For this reason it'd be best if you try to make your own unblocker instead - you can find instructions on how to do this here: How To Make A Proxy

How does it work?

Unblockers are like a gateway that pass information between your computer and the site you're trying to visit. The unblocker accesses the site you want on your behalf, loads the page, and sends it off to you. So the site you want to access never sees your IP. So, basically you are surfing websites in an indirect way. School firewalls think you are just visiting the unblocker, not the site you actually want.

An alternative way to unblock YouTube in school is by setting up your own unblocker site. This is more complicated than using an unblocker but it's a lot nicer to have because if they block it, you can make another. How to do this is too much effort to explain here, but you can find instructions here: Unblock YouTube at school. You can even make some money from your unblocker by letting people advertise on it.
