Ads with animals

Okay, so this totally ain't science.  But they use animals!  Good HD action in them, too!

More physics

If you liked the sublimation of hot oil shown by William Shatner in my other posted video, you might be a physics nerd. Here's a video (in real time!!) of what happens if a railroad sealed container isn't vented properly.  It was emptied out and the hot gas remained inside, displacing volume.  The gas cooled, reducing the volume inside.

Safety dictates that the workers would have to keep a vent open after emptying it to avoid this problem.  This was a safety demonstration to show the public the power of our atmospheric pressure!

Note that air pressure works differently from gravity.  If you forgot in what ways, you can watch this.  Note that not everyone has a great control over gravity.

Five Minute University

Oh, I can't believe I left this out!

Father Guido Sarducci was a hit on Saturday Night Live.  I don't know what other classic bits he's put together, but I must say this is my favourite by far!

The cyber-conductor

My kids are playing at the Jubilee Auditorium tonight for the Kiwanis festival.  It'll be a long night:  they start at 4 pm and go to 9:30.  Penny's out of town tonight, so it's just us three... I'll take the kids out for a treat afterwards.  I know Tim's a bit under the weather - had a sleepover on the weekend (therefore no sleep) and then went skiing with his class yesterday.  A total phlegmball today.

So I was happy to see this cute piece to show them when we get home!  Thanks to Rob Willard, a friend from Stampede band a few decades back, who put this on his Facebook page!
