[quote=Rustico]Rustico happens to have a very fun 4 year old and a bag of marshmallows. He did five minutes no problem but played with the thing for the last three minutes. First is was a prosthetic nose, than a thumb ring etc. When he got the second one he just kept playing with them and finally shoved both of them in his mouth in one last great burst of goofiness.[/quote]

How fun! My kids are 7, 9 and 11 are beyond the allure of marshmallows. I think the version for them would involve putting them in the car and telling them not to tweak/bug each other for 10 minutes. The question is what reward would be offered? Allowing them to bicker without intervention for 20 minutes? I don’t know if I could stand it. . .
