Waste not
Invent a way to help people waste less food.
No waste ideas
Nearly a fifth of the food we buy ends up in the garbage! And lots of that is food that is perfectly edible, but still we throw it away because we prepare too much or we're not sure about how fresh it is. Invent and draw your very own ingenious ideas to help reduce the food you throw away at home! Upload them to show the world!
