a different Easter chalange

For years I have hidden plastic eggs filled with candy and money for my four grandchildren to find on Easter Sunday.  I even hid them at my daughter's house when she hosted the dinner.  This year Easter dinner for eleven people will be in my apartment and I've decided that, since the grands are all teens now, I will try a different kind of treasure hunt.  I have taken eight $5 bills and hidden them around my apartment with just a tiny bit of the bill showing. For example, one bill is folded up and peeking out of the slot of my piggy bank, another is rolled up with the edge sticking out of a small vase.  Their challenge, if they don't think they're too old for it, is to find the money. They can help each other hunt but they each get only $10.  Those are the rules. I hope they enjoy the hunt, and, by the way, I have made a list of the hiding places just in case. I wouldn't want to outsmart myself.  Now if I can just remember where I hid the list.
