Unblocked Videos Does Anyone Know A Site Where You Can View Videos On A School Computers?

Does anyone know a site where you can view videos on a school computers? - unblocked videos

Some sites show that the videos were made, but the video shows an overview and a small black box is only displayed when the mouse pointer. Can anyone help me with that? because me and my freinds want to anime-see teams in the school and require many pages to a flash drive or computer, students are allowed somethingand not for this download.
Thanks in advance!
