April Fools' Day with Seth Meyers
It's April Fools' Day, and the hilarious Seth Meyers ("Saturday Night Live") is joining Martha in the kitchen to make a rhubarb fool, a deliciously tart treat the whole family will love. Then, crafter Diane Phillips of San Francisco's DK Designs shows you how to make stunning flowers out of lightweight clay, a one-of-a-kind way to decorate your home for spring. And, Tim O'Brien, vice president of publishing and communications for Ripley's Believe It or Not, is here with some amazing art that fools the eye. Plus, Cupcake Week continues with Karen Tack, author of "Hello Cupcake," and some wonderfully whimsical cupcakes that may just make an April fool out of you!
