The Olympic flame isn't fire. So what is it?

The Olympic cauldron at the 2024 Paris Olympics features a unique design that creates the illusion of fire without using actual flames. Instead, it utilizes clouds of mist and beams of light to simulate a "ring of fire" that rises approximately 200 feet into the air, supported by a balloon-like structure. Designed by Mathieu Lehanneur, the cauldron's concept draws inspiration from France's historical achievements in flight, particularly the first manned hot air balloon flight in 1783. Lehanneur emphasized that using a real flame at such heights would pose safety risks and require significant gas, contributing to carbon emissions. The flameless design aligns with the Paris Olympics' goal to reduce the carbon footprint compared to previous games. The cauldron has become a popular attraction, with 10,000 free tickets available each night, all of which have sold out. Spectators have expressed their emotional responses to the spectacle, with many feeling proud of the event being hosted in Paris. Lehanneur noted the unexpected positive feedback from the public, contrasting with the stereotype of French people being critical. There is potential for the cauldron to remain in Paris after the Olympics, as the city's mayor has expressed interest in finding it a permanent home.
