Thousands are gearing up to participate in Shabbat UK's Great Challah Make at London's Allianz Park. But the amount of flour in the room has raised concerns about health and safety.
During a practice run last week, event co-chair Dalia Cramer pointed out that everyone pouring their flour into their bowls at the same time could create a cloud and set off the fire alarm.
Perhaps organisers should instead relocate the bakers on to the adjacent rugby pitch for an al fresco experience.
