We borrowed this idea from my son's preschool. Perfect snack for in the car or stroller since it makes it extra complicated to drop them all over the side walk! Of course, where there's a will, there's a way!
Not to mention it occupies them for 30 mins...quietly.
ps...you could always have them string up rigatoni instead of cereal...then its the motor skills they are learning, vs eating sugar!
