What better way to sell a $400 USD blender than show it blending all sorts of household items. Going back to the good old days of advertising where people actually demonstrated the products in the ads.
My fav is the bag of marbles into dust.
They've put together a site called Will it Blend (much more interesting than the Late Show's Will it Float) which contains all the videos and product information.
It's certainly entertaining and will put the Blendtec brand in front of millions of people without them having to spend millions on product placement, endorsements or traditional media. Great work.
