Well, as long as five new DVDs is considered mad it’s madness. All kinds of bases are covered by this selection, and here they are…

Best of Dangerous Encounters with Brady Barr follows a reptile expert as he does all sorts of silly things in the name of science.  My favourite bit is when he wears a 200 pound kevlar suit covered in hippo dung to extract sweat from a hippo.

The Most Extreme is a series that follows all sorts of extreme behaviour in the animal kingdom. Fighters, Stinkers, Gluttons and many more are looked at in these fantastically shot episodes originally made for Animal Planet.

Sticking with the extreme, Gravity Games H2O is a four disc box set filled with wakeboarding, tow-in surfing, motorcross, kite surfing and other assorted watery hijinks. Except for the motorcross, I can’t explain it’s inclusion unless they somehow ride on water. Now that’d be extreme.

Ultimate Factories is a National Geographic series that goes to, well, ultimate factories. In this one they go see how Ferraris and M1 Tanks are produced. So if you’ve ever wondered how they put them together, now you can find out.

Naked Science: Surviving nature’s fury is a three disc set in the excellent National Geographic Naked Science series. These episodes look at asteroids, the Bermuda Triangle, alien contact and other popular and controversial scientific topics.
