Teenage enquiry: "Hey I wonder if you can not bother with the bowl and just have the cereal and milk straight from the box?"
I can report that the experiment, admittedly being unrepeated and only drawing from one result, was a resounding NO (unless your aim was a considerable redistribution of milk around the room).
Love it!
Oh yes you can!
Well you can if you use the individual portion packets. Have done this for years when camping as it saves washing up.
