Synthetic diamonds that fool the experts, L.A. on foot, a website for the philosophical, and more.
This Saturday, join Aretha Franklin, Barry Manilow, host Jimmy Smits, and a cast of Muppets in Washington for PBS's 29th annual "A Capitol Fourth." The event boasts the nation's most spectacular fireworks display and offers musical talent to suit all ages, including Natasha Bedingfield. The National Symphony Orchestra will be on hand to set the tone, while Kermit and crew can be expected to lead a national singalong when it comes to the patriotic tunes. Yankee Doodle Dandy, indeed.
