Re: Have seen "Sensitive Weed" , or know what it i
i haven't used google for this, but I think i know what you're talking about
it's a kind of plant that when touched it just closes like a clamshell, it has small leaves in a 5 or 6cm stick (never got to look for the english vocabulary for this kind of stuff ), it's pretty fun, but it's just the plant's defence mechanism.
