The unusual stunt happened in the south-western Russian city of Penza where two videos of the teenagers launching themselves from the bridge were shared online.
The first video starts off by showing a teen being doused in a flammable liquid before a friend puts a lighter to his coat to set the boy alight.
Thrill-seeking teenagers jump from bridge while set alight
As the flames quickly engulf the lad he jumps from the bridge and makes a splash as he lands in the water below.
The second video was filmed from the ground and shows two burning daredevils jumping from the same bridge, almost in tandem, much to the delight of their onlooking friends.
The two boys can later be seen swimming in the water seemingly unharmed after they leaped.
One of the thrill seeking youngsters said he jumped to get more likes and views on social media. He didn't mention a desire to gain the adrenaline rush that undoubtedly comes from jumping from a bridge while on fire.
'We did it for the likes on social media. We took the idea from a blogger. We made a bet with our friends and jumped off the bridge. We wanted to get a lot of views,' he said.
The police are checking the circumstances of the stunt and have reportedly arrested one of the pair.
