I'll explain the challenge.
Today's challenge is called "Rainbow Bid."
The colors of a rainbow are red, orange, yellow, green, blue, indigo, and violet.
In front of you are giant blank pictures of a rainbow, as well as $500 in cash.
One-by-one, I'll take out a marker of one of the colors of the rainbow, and it is your job to bid on one of them. If you get that marker, you can fill in a section of your rainbow. Once all of the colors are bid on and received, the person who has colored in the most sections on their rainbow will win immunity.
It's your job to decide when to bid and how much.
You cannot pool money or share markers. Any questions?
