I haven't found a use for them so I just recycle them with our other plastics once a month. I make sure I peel the labels off first. Our garbage company takes plastics numbered 1-7!
I like them because the days are labeled and I can remember if I took my pill that day. I also take the plastic foil thingy out (don't know what it's called) and throw it away before recycling. ... View related article.
Our bible school this year is cowboy themed too. Here are some of my ideas:
Sheriff badges made from empty pringles containers. Cut down the side of the container and cut off the bottom. Then you have one big piece of silver cardboard. Make star shapes on the opposite side of the silver cardboard. I got 9 stars per container. Hot glue pins on each star and use them as name tags for the kids and helpers.
Cactus piggy banks made from an empty juicy juice container. Paint it green and hot glue on green foam for the arms. Make eyes, nose and mouth from an old egg carton and glue on. I used a scrap piece of tissue paper for his bandana and glued on a star for his badge. Found an old straw hat in my craft drawer for his hat but for VBS will make cowboy hats from styrofoam cups that you melt in the oven. Here are the directions: http://www.freekidscrafts.com/styrofoam_cup_spring_hats-e331.html Then paint the hats brown. Cut a slit in the back and you have a cactus bank. Here's a picture of the cactus.
