As Russian companies try to cash in on football-themed products ahead of the 2018 World Cup in Russia, one popular water brand is literally trying to catch fire. Just about everyone is trying to capitalize on the tournament kicking off in 11 Russian cities two weeks from now, luring fans with customized souvenirs including sausages and Matryoshka dolls salaciously blowing the referee’s whistle.

Bottled mineral water maker Svyatoi Istochnik is no exception, coming out with a new football-shaped commemorative bottle that was quickly discovered to have a potentially deadly design flaw. Leave the plastic bottle in the sun long enough, it turns out, and its unusual shape will redirect the sun’s heat like a magnifying glass use by kids to burn ants.
