Imagine that you need to remember to take your lunch bag with you, when you leave the house.  Put it on the edge of a counter or table such that a good portion of it hangs off the edge.  The more precarious, the better (as long as its center of gravity will keep it from falling off!).  Like the visual reminders that rely on unusual images, your eye will be drawn to the risky situation and you’ll be more likely to see it and take it with you.  Good for anytime you need to take something with you (from one room to another, or leaving the  house) and the size and shape of the object allow it to be placed in a way that looks unsafe but is actually OK.
