way to use the baby juice bottles!!!

Ok so I am trying to teach my kids that saving the environment is important. So I try to show then ways to make projects out of things we would normally throw away. So juice bottles...well I am growing my own herbs this year. I thought what the heck am I going to store them in? well Why not use the juice bottles? when you dry your herbs they will fit perfectly in the glass or plastic juice jars and you have lids so it is perfect.
