In many parts of the world it is common practice for people to balance and carry on their heads to to free thier hands. We're quite sure you have never seen someone carry something on their head while riding a bike.
Somewhere in Sao Paulo, Brazil a man is captured on camera casually riding his bicycle with what appears to be a metal gas canister on his head. You can't tell if the tank has anything in it or what materials it is made from, but the fact that this man is doing all this while pedalling around on his bike is amazing.
As he appraoches a stoplight at a busy intersection he continues to balance the container on his head while a stranger captured it all on camera.
