Visitors to Science North can now experience what it feels like to weigh less on other planetary bodies with the launch of three new interactive gravity chairs, located on the science centre’s fourth floor.

Developed in partnership with Cambrian College, the custom chairs allow visitors to physically experience the difference in gravitational forces on Earth, Mars and the moon. Using a rope and pulley system, participants pull themselves upward while seated, simulating how much lighter they would feel on other celestial bodies. A built-in motor ensures a smooth and safe descent after each lift, making the experience accessible and engaging for visitors of all ages.

“This project is a great example of what can happen when education, innovation and community partnerships come together,” Ashley Larose, CEO of Science North, said in a release. “The gravity chairs give visitors a fun, physical way to understand planetary gravity while showcasing the incredible talent and creativity found right here in Northern Ontario.”
The chairs were designed, tested and fabricated by students and staff at Cambrian R&D, the applied research division of Cambrian College. The collaboration allowed Cambrian students to apply their engineering knowledge and skills while showcasing their work in Northern Ontario’s largest tourist attraction.

“This project was such a great way to expand the scope of the applied research partnerships and initiatives we do at Cambrian R&D,” Kristine Morrissey, president of Cambrian College, added. “What a terrific experience for our students and staff who worked on this, who can feel that sense of pride every time a visitor to Science North tries one of these chairs.”
The exhibit also connects to the excitement surrounding Artemis II, the mission that sent astronauts around the moon. The four-person crew included Canadian astronaut Jeremy Hansen, who became the first Canadian to orbit the moon and travel further into space than any human before. Although Artemis II did not land on the lunar surface, the mission tested the new Orion spacecraft and marked a major step forward in human exploration of deep space.
With the new gravity chairs, visitors can experience a small taste of that journey and discover how different the universe can feel beyond Earth.
The chairs are now open to visitors in Space Place at Science North. The exhibit is included in general admission to the science centre.
