A funny video has emerged of teenagers using a giant skill tester at a birthday party, and electrocuting themselves in the process.

The footage, shot on Monday near Sydney, Australia, shows the guests trying out their skills on the custom-made game which is plugged into a 12volt battery.

The contraption was created by the father Jacob Strickling from the YouTube channel 'Make science fun'. He did it for his son's 18th birthday.

"The teenagers had a great time and the pain only lasted a short time," he wrote online.

It's worth mentioning that Jacob knows what he's doing and this is not something to necessarily try at home.
