Can you tell me the plant name ? ?

Question

it has a small long thing on the leaves that when you touch it goes POP and curls up in your hand me and my bros use to have great fun with them long time ago id love to know the name

Answer 1

There are quite a few seed pods that have that popping action to disperse seeds.  Impatiens, or Touch-me-Nots, are one kind.

If you could post a picture, we'll be able to narrow it down.

Answer 2

What part of the world do you live in? Be specific because it sounds like a native plant (since you say it grows near ditches).
