Lots of sugar and no chance to hit a sweet chemical product where you want it, into a cup (with tea). At least not yet. Your task is to create on a playing surface with a line, a system of lines, such conditions to hit falling sugar at specific sites. Lines must not only have sufficient slope and length, but also the exact location. Indeed, when you have more cups, but with the condition that sugar has the same color such as that mug, your brain will just have to be more alert. It's not just about drawing a line :-).
