Silly strings

Since today is Naomi's birthday, Nathan really really wants to spray these silly strings on her. 

We thought we would start with spraying a paper box first. 

 A birthday cake....sort of.

 Well, if we spray on the ground, we need to pick them up

 Now Nat Nat is ready to spray at Naomi, according to the instruction, 3 m away. 

 SPRAY..........

 ........AWAY.........

 Now what?  Who's gonna pick them all up now?

 Clean up time
