Weigh the Wangdoodle

Okay so I'm not sure if this will link but this is pretty much a sweet game i'd say. This is the website at least -> http://www.mathplaygroung.com.wangdoodles.html/ I think it's kind of hard, but I know Mr. Maksymchuk will get it fast; but if you're not that bright like me it'll take a while. What you have to do is figure out the weight of the wangdoodles to make all of them balanced on all three scales.
