Chocolate-Scented Tube Advert Sparks Nausea Concerns Among London Commuters
A multi-sensory advertising campaign for Magnum ice cream, which pumps out a chocolate aroma at a busy London Underground interchange, has ignited significant concerns among passengers and Tube staff. The advert, installed in a tunnel connecting St Pancras railway station and King's Cross St Pancras Tube station on Monday, aims to engage commuters through scent and sound but has instead provoked widespread discomfort.
Passenger Reactions: From Nausea to Confusion
On social media platforms, commuters have voiced strong objections to the overpowering chocolate scent. One Reddit user described the smell as "far too strong and makes me feel a bit nauseous rather than making me fancy a magnum, although they have got us talking about it." Another likened it to a "weird artificial chocolate smell like a chocolate-scented bubble bath," adding that it was "not really appetising at all, I don't like it."
Further complaints emerged on X, where a user questioned, "Much as I love those chocolate cherry ice cream bites, is the advert at Kings Cross/St Pancras tube tunnel making everyone else somewhat nauseous? You can smell the chocolate + disinfectant(?) all the way down to the tube platforms..." Bob Bounds echoed these sentiments, stating, "I can attest to this - and my sense of smell is terrible. The sickly smell pumped out is awful, and stays with you. Marketing gone mad."
Staff Complaints and Operational Disruptions
Transport for London (TfL) workers based at the Tube station have reported that the chocolate scent infiltrates their break room, leading them to lodge formal complaints with St Pancras station management. The advert, which also features a cracking sound to simulate biting into chocolate-covered ice cream, has created an unwelcome environment for both employees and passengers navigating the interchange.
Responses from Magnum and Transport Authorities
A spokesperson for Magnum Ice Cream Company defended the campaign, saying, "The Magnum activation at King's Cross St Pancras recreates the multi-sensory pleasure of enjoying a Magnum through sight, sound and scent, and is designed to bring a moment of enjoyment for commuters. Since the campaign began on March 9, we have received mostly positive feedback from commuters onsite and will continue to optimise the campaign which is scheduled to run until March 22 based on consumer feedback. Our intention remains for our campaigns to be engaging and enjoyable."
In response to the growing concerns, a TfL spokesman confirmed that the transport authority is aware of the issue and has raised it with Network Rail, which holds responsibility for the area where the advert is located. This incident is not isolated; in October 2024, Network Rail faced similar scrutiny when then-transport secretary Louise Haigh ordered the removal of a 15-metre advertising screen above the concourse at Euston railway station due to public concerns. Network Rail has been approached for comment on the current situation.
The controversy highlights ongoing tensions between innovative marketing strategies and public comfort in high-traffic transit hubs, raising questions about the limits of sensory advertising in confined urban spaces.
