It will blow up but if it’s not shaken up it takes a couple minutes so more than likely it will pop way before you ever see it. It’s not going to kill you or blow a finger off even if you did pick it up. My advice if you see a bottle with something weird in it just walk away and wait a little while because it will pop on its own. This is coming from someone who loved to blow stuff up as a kid. I’m lucky to be alive now.
