Much of America's Midwest region is experiencing an extreme cold temperature owing to polar vortex. The temperature plummeted so fast that the Chicago River has been frozen and to make sure trains were running smoothly, officials had to set fire on the tracks to keep it snow and ice free. The sub-zero temperature has forced most Midwesterners to stuck at home this week, but looking at the social media, it seems boredom has led to some bizarre challenges and stunts online. Most that involve throwing boiling water in the air as it freezes instantly, yes, a cool science experiment but if not done right could be harmful.

It's freezing cold outside but for the thrill and some social media fame, people are braving the cold and going outdoors to throw hot water in the air and watch it fly away as frosty vapours. In case, you're interested, it's a scientific phenomenon known as the Mpemba effect.

Boiling water droplets quickly freezing into ice crystals. -19 degree fun. Caution: boiling water will burn if not careful. pic.twitter.com/hJ3doP48nn — Finley Math (@FinleyMath) January 30, 2019 #PolarVortex Or as we call it in Minnesota.Tuesday Embraced my inner 6 year old at -33F earlier today pic.twitter.com/5P3Ht3WWy3 — Andy Potter (@stalefarts) January 30, 2019 Boiling water.

Some, however, retain shape and land frozen. pic.twitter.com/Mn4WzDTB81 — Gregory Humphrey (@dekeriverscp) January 30, 2019 Sadly, the boiling water experiment did not end well with many and instead of frostbite, they ended with burns and blisters.
