The special, World Cup-themed soccer ball-shaped bottles have proven to be the perfect shape to start fires by concentrating the sun's rays.

Russian supermarket chains Ashan and Lenta had pulled the ball-shaped Svyatoy Istochnik (Holy Spring) water bottles after it was reported that they could cause fires.

A video by St. Petersburg-based news portal Fontanka.ru shows how the bottle can combust nearby objects when placed in direct sunlight.

As might be expected, social media had a field day with the defective water bottles.

"Holy Spring creates bottles which work like a magnifying glass."

"Holy Spring are inventive in general in terms of bottles guys."

"After finding out that these bottles can burn everything to hell."

"This bottle would be useful to take on a hike; you can start a bonfire with it. I'm not joking. Don't bury an idea before its time."
