Celebrity chef Jamie Oliver is attempting to break a world record for the most people ever involved in a 24 hour cooking lesson.
9,000 schools around the world are taking part and will be attempting to make the same dish.
Organisers hope the record attempt will help teach children how to cook and make healthy food.
Nel has been at a school in London that's taking part.
