That, and I've never been a huge fan of a plain marshmallow. Throw some chocolate and graham crackers in that room and it's a whole different story...
"In this popular test, several kids wrestle with waiting to eat a marshmallow in hopes of a bigger prize. This video is a good illustration of temptation and the hope in future rewards. This experiment is based on many previous and similar scientific tests."
Ahh, the struggles of a young mind.
