Today I was looking for a glass pot for K's French press at the Bijenkorf, an upmarket department store (himself prefers Bodum) and found something for myself too.
This is Arian Brekveld's Fresh Traveler a way to take cereal (in the bottom compartment) and milk or another liquid (in the top) with you to have breakfast somewhere else. I've been thinking about this for some time, whether I had some type of suitable tupperware box to take with me, but then I'd have to pre-mix the ingredients and the cereal would go soggy.
So now I'm going to get up tomorrow morning, fill the top with cold yoghurt and take it with me. The bottom already has summer cruesli (with apple and raspberry), which I will poor onto the yoghurt on the train or at work, achieving the perfect combination of crispy cereal and cold dairy.
