I made this for my nephew back in MN. I took a 2 liter bottle of pop and washed it out and filled it with a few things for my nephew. I put a flashlight, monster truck, some stretchy bugs, a sun visor, and a box of animal crackers inside. I cut the bottle with a box cutter in three places to make a three sided "door" in the bottle. Then I put the paper inside and filled it with goodies. I used packing tape to close it and taped on an address label cause I am sending it to him in the mail. Cute ha? I added the ribbon just for the picture I am not mailing it with that on it. I have another one that I am making that will not be mailed. For that one I am going to fill it with stuff and then add paper around the bottle to decorate it. I didn't decorate this one on the outside because it is getting mailed. These are fun to give as birthday gifts. For girls you could fill it with a hair brush, some scrunchies, and barrettes. Maybe a stuffed animal. You could put what ever fits inside. They are fun to make and I bet super fun for the person that gets it to try to figure out how to get their stuff out. For the one I am not mailing, I am not gonna tape it closed. That way when they take off the paper around it they can get to their stuff easily. I would also suggest that if you are mailing it I wouldn't put anything "appealing" inside that people can see, so that no one takes it. I got most of the things inside mine with stuff from the $1 spot at Target.
