Time Bomb

I have two bindweed vines in my back yard. I did not plant them they volunteered. I have just welcomed them. A couple of years ago the older one began producing seed pods. These are large and I think they are kinda creepy looking. The first year I just cut them off because I don't want bindweed all over my back yard. Last year I decided to save some to see what happened. Well the pods opened and A LOT of seeds came out but they were in a very ordered pattern so this year I decided to see what would happen if I put them in sealed frames with glass in front. So I am calling them time-bombs because this is the before state and I am pretty sure there will be an after state. Right now they are just creepy pod things that look kinda cool.
