It's national bubble week! Elmo, Rosita, Zoe, and Charlie are filling all of Sesame Street with bubbles to celebrate. They try blowing bubbles and waving a rope to make more bubbles but their lips are arms are getting tired. They wonder if there's something that could make bubbles for them. What if they put bubble wands on an egg rack in front of a fan and spin it through a tub of soapy water? Let's try! It works. They didn't give up and Sesame Street gets filled with bubble with their new bubble machine!
