The discussion centers around skepticism regarding a claim that water can be lit on fire. Participants argue that the demonstration likely involved a flammable substance, such as white gas or lighter fluid, rather than water itself. One contributor suggests that pan searing flour, a fine powder, could have burned instead of the water. Criticism is also directed at the video's production quality and the incorrect assertion that water boils at 195°F. A related anecdote is shared about an experience in New Mexico where hikers reportedly lit water due to dissolved natural gas, suggesting that while water itself cannot burn, certain conditions may allow for flammable vapors to ignite. Overall, the consensus leans toward the demonstration being a trick rather than a genuine phenomenon.
