This is a cute project for the kids, or even the adults!
You can keep vacation memories a little stronger a little longer with vacation memory jars. Filled with souvenirs collected on trips and pictures developed afterward, they are like little worlds that can be visited again and again. Kids can also add to them or rearrange them anytime they like. Bent wire can be used to lower and position objects in a thin-necked jar.
here are a few more vacation jars I found online.
If you travel often, you could have one for every trip!
