so, I'm with my friend sheraze chatting, and we've found that concrete (yes, the one hard as rock, to build the house) can do many things.
Concrete is like a superpower -Shéraze
yes it is.
it's all started when we found this
How to Open a Can Without a Can Opener
Method 4 Using a Rock or Concrete
i'm shocked when saw this method, and don't believe it at all, so does sheraze.
but still decide to try it, so after a few seconds, the can opened, it works?!!!
this shocked us.
second part later
