Mt. Etna in Italy Blows Smoke Rings [VIDEO]
One of the most seen images this week were from Italy where Mt. Etna was literally blowing smoke rings! Apparently, smoke rings are extremely rare and have only been documented three times. And what’s even more weird is that this is the third time Mt. Etna has blown smoke rings. The last two times were in 1970 and 2000. The only other occurance on record happened in Iceland last year from Eyjafjallajokull. The BBC has more on this natural phenomena here.
