Rainbows Smell Like ?!?!?!

Did you know that rainbows smell like... LOL!! I didn't know they had an odor, but the other day Nathan and I had a conversation that went like this:

Nathan: Mommy look...a rainbow!!
Me: Very cool!! What are you doing??
Nathan: (laying on the floor with his nose pressed to the carpet) Smelling it!!
Me: What does it smell like?
Nathan: Smells like ICE!!

I had no idea that rainbows smelled...much less smelled like ice!! LOL!!
