How can kayaks float if the material they are made from is denser than water?

many kayaks are made of plastics and other composite materials that are denser than water, so how are they able to float in water?

Bernouli's Principle says that a body in a fluid is bouyed upward by a force equal to the weight of the displaced fluid. A kayak (or a steel ship - or, yes, even one with a hull made of concrete - will float if it pushes aside (displaces) water which weighs more than it does. That really is the function of the hull of any floating craft: Push aside the water so the displaced water will support the hull and its contents.

Amarantine $2.17 From the first blanket of choral voices awash in reverb, Amarantine is instantly recognizable as a product of Enya, the Irish chanteuse who has created a genre unto herself.

Last Waltz [VHS] $5.55 Martin Scorsese's 1978 capsule history of the Band is mixed with footage of the group's allegedly last performance (certainly their last performance as a quintet) in this particularly stylish concert film. Scorsese shoots the players and their sundry guests with the same flair and enthusiasm one can see in the later The Color of Money or Goodfellas. He also proves a good interviewer with Band memb...

Waterworld [VHS] $1.89 Let's be honest: this 1995 epic isn't nearly as bad as its negative publicity led us to expect. At the time it was the most expensive Hollywood production in history (it had a Titanic-sized $200 million budget), and the film arrived in theaters with so much controversy and negative gossip that it was an easy target for ridicule. The movie itself, a flawed but enjoyable post-apocalypse thriller, de...

Thicker Than Water $11.99 On its second album, H2O tightens up its sound, dumping the ska experiments in favor of their love of melodic speed-punk and classic hardcore ? la Minor Threat. There is a positive, straight-edge sensibility to most of the lyrics, but singer Toby Morse never comes off as preachy or didactic. The riffs are strong as well, making Thicker Than Water a fine effort. ~ Steve Huey

Thicker Than Water - $5.99 While going through the possessions left behind by her recently deceased father, a prominent and well-respected judge, High-powered attorney Natalie Jones (Melissa Gilbert) is shocked to come across a worn, yellowed snapshot showing her father in a warm embrace with famed rodeo trick rider Maggie Mae Jarrat. It soon develops that, unbeknownst to Natalie, Maggie and her dad had once been married. Hoping to get the full story, Natalie leaves her cosmopolitan surrounding and heads to wild horse country in Longmont, California, where she meets the late Maggie's gritty, tough-minded daughter Jess (Lindsay Wagner). The bond that slowly but surely develops between the two women leads Natalie to champion Jess' cause when greedy rancher Tom Grove (Grainger Hines) and his cronies begin killing off Jess' free-roaming horses so as not to "mongrelize" their own purebred stock. And, as a bonus, Natalie falls in love with dedicated local veterinarian Sam Nelson (Brian Wimmer). Made for cable, Thicker Than Water debuted March 12, 2005 on the Hallmark channel. ~ Hal Erickson, Rovi

Is Blood Thicker Than Water? $11.99 From Pulitzer Prize-winner James M. McPherson comes a brilliant and passionate examination of nationalism in today's world, and its effects on the stability of the world's countries, big and small. Since the end of the Cold War, nationalism has re-emerged as one of the most powerful forces in the modern world. Students of nationalism have analyzed two principal categories of this phenomenon. Ethnic nationalism is more familiar and easier to define; it broke up Yugoslavia into four mutually hostile ethnic nations. It split Czechoslovakia into two nations. It threatens to do the same to Canada. In contrast, civic nationalism defines national identity not by presumed descent from an ancient bloodline with its own language, culture and genetic purity but by citizenship in a national state and loyalty to its political institutions. James M. McPherson focuses on the American Civil War and Quebec's bid for separation from Canada as case studies in the contest between these two strains of nationalism, and offers both implicit and explicit comparisons to modern counterparts. Is Blood Thicker Than Water? will finally give us the perspective to look at this phenomenon clearly and objectively. From the Trade Paperback edition.
