Go download VideoDownloader 2.0 for Firefox (There might be a more current version I don't know) read the instructions and you should be able to download the video, albeit in an FLV format.
It's weird though, the bomb threats are always in the bathroom. So far in my life of education I've had two maybe three bomb threats? Every time it's a letter found in the bathroom. Actually, this one kid from my school decided it would be funny to joke around about bringing a gun to school on Facebook, this guy from Texas (I go to school in New Jersey) saw the kid's comment and reported it to the police, the kid was expelled and sent to a juvenile detention center for a month or so IIRC. Kids who do this are just stupid.
On a side note. Hahaha your school gets a family fun night? I can't imagine who attends those things, no offense to you esa of course if you go to that.
