Situated on the South Bank by Tower Bridge, the activation features an open-ended, weatherproof structure, which houses The Flash Pack’s 360 Bullet Rig technology.
Passers-by are being invited to stop by the space until 10pm on Thursday (21 January) to create their own 360-degree videos, which can be shared directly to social media.
Two large video screens have also been installed nearby, showcasing a selection of photo booth creations and Third Space content, with the aim of encouraging passers-by to stop off and take part in the experience.
Jerome Maas, managing director of The Flash Pack, said: "The Bullet Rig can capture great fitness related content; it is a fun way for guests and prospective members to interact and get active. Here we create unique images that capture both the movement and the vibrancy of the Third Space brand, making for some highly shareable and fun but relevant content."
