While they were working, Steve the astronaut’s phone started ringing. It was his daughter Ruby calling from earth. He picked up his phone and answered.

“Hi Ruby. You know it’s almost your birthday.”

“I know,” Ruby told her father. “That’s why I’m sending this picture of the rainbow cake I want for my birthday.”

Holding the phone up in the air so everyone could see, Steve the Astronaut shouted. “Hey everybody look at the picture of the rainbow birthday cake we are having for my daughter Ruby’s birthday party! You are all invited. Come on out to the party and have a piece of rainbow birthday cake with us.”
