Episode Summary

It's Bubblefest on Sesame Street! Telly is excited, but blows too hard and can't make a bubble. Rats.

In the meantime, Alan and Chris pose a question: What is the perfect bubble mix? Elmo and Abby try to figure out how much water, soap, and corn syrup to combine, using different size cups to measure. Testing their mixtures, they find the best one.

Then there's a Bubblefest Riddle: "What's round and wet, is something you blow, and has all the colors of the rainbow?" Alan and Chris show that bubbles are iridescent: lustrous and rainbow-colored. For the Bubblefest Finale, Abby and Elmo use a hula hoop to create a bubble so big a child can fit inside.

And then…Ta-da! Telly finally blows a bubble. The crowd cheers!
