What is this crazy lookin' bean?

Our first backyard mystery to solve is about this funny looking bean that grows off a vine by our grandparent's pool.

When you open it up it has these seeds in it. It was also wet and sticky on the inside. The question we have is - if you plant the seed will it grow? We know it's part of a Wisteria Vine. We have done a little research and found that these seed pods will help to grow a new vine, however, they are poisonous!! Good thing we didn't eat them!!!!
