Did these guys just put a tire back on a rim with a firecracker?
Yes, they certainly did.
Watch this video that proves fireworks might just have survival situation uses.
Word of warning: never try this at home. These guys still have their fingers and eyes, but you may not be so lucky.
This video shared by Racing and Racers on Facebook shows quite an interesting trick. They put a firecracker inside of a Jeep tire that is separated from the rim. With pressure placed by one man pulling the tire, the exploding firecracker actually pops that tire back on the rim incredibly.
All fingers accounted for, so we would say this experiment was a success this time.
