Groucho Marx once famously quipped that he'd never "want to belong to any club that would accept me as one of its members." Most people would probably say the same about the Martin-Baker Ejection Tie Club—a very exclusive, 63-year-old organization created specifically for individuals who have had their lives saved by an ejection seat. Currently, the club boasts more than 6000 members.

That's just one of the weird and wonderful clubs you'll learn about in our latest edition of The List Show. Join Mental Floss editor-in-chief Erin McCarthy as she hunts down the world's most unusual clubs (Extreme Ironing Bureau anyone?). You can watch the full video below.

Mexico is home to 48 active volcanoes, but few can compete with Popocatépetl. Located around 40 miles southeast of Mexico City, it's one of the most active volcanoes in the country, and on January 9, the extent of its power was caught on camera.

The video above, reported by NPR, shows the Popocatépetl stratovolcano—also known as a composite volcano—spewing lava, ash, and rock in a fiery plume that reached 20,000 feet above its cinder cone crater. CENAPRED, Mexico's National Center for Disaster Prevention, filmed the volcanic eruption as it unfolded early Thursday morning. The National Oceanic and Atmospheric Administration also recorded the explosion from space using its GOES 16 satellite.

#GOESEast recorded the #eruption of #Mexico's #Popocatépetl #volcano this morning (which spewed an #AshCloud ~20,000 feet into the air) via its #GeoColor band. It also detected #SulfurDioxide in the #plume, as shown in the second SO2 composite.

No one was hurt by the incident last week, but CENAPRED is warning people to avoid the area as debris continues to fall from the summit. The center has set its Volcanic Warning Light to Yellow Phase 2, which indicates there's no immediate threat of danger.

Since it emerged from dormancy in 1994, Popocatépetl, or "El Popo," as it's known by locals, has become one of the most active volcanoes in Mexico. Tremors and showers of ash are now regular occurrences for residents of nearby towns. Given its volatility, there are currently 20 devices monitoring the volcano 24/7.
