The most expensive animal protection suit ever made, according to that bastion of knowledge, Guinness' World Records (the television version). They had a rather amusing video of this suit in action.
Apparently, the bear protection suit not only protects you from bear attacks, but also from being beaten with baseball bats, hit by cars, and clobbered by swinging logs. It also has the added bonus of making you look like Robocop.
However, it's clearly meant for research purposes only. Take this (true!) scenario as an example:
A researcher, wearing the suit, looking formidably like Robocop, lies in wait in a pile of garbage. He knows there are bears nearby, and knows that they will come to feed on the tasty refuse. He's prepared to study their behavior, with a video camera hidden nearby.
The bears approach, and appear to be surveying the territory. One of the bears pokes around in the trash heap near the researcher. Despite knowing that his suit can protect him from nuclear warfare, the researcher promptly reaches up and punches the bear in the nose.
The bear retreats, and the research is, apparently, complete.
I think that the moral of the story is, the best way to study a bear is to punch it in the nose. Why do I get the suspicion that this was funded by the government?
