A new trend has made its rounds on Russian social media in recent weeks called "The Dubak Challenge," (from the Russian дубак, a slang word for intense cold) in which boiling hot water is thrown into sub-zero air for a beautiful sight. The result comes from the Mpemba effect, in which hot water freezes faster than cold water.
Warning: While the effects are tempting, the process is a risky one. We strongly advise you to not try this at home.
When hot water meets freezing air meets sunlight.
Many of those up for the challenge experimented with different angles and effects.
A video in slow motion shows the reaction between the boiling water and the cold air as it happens.
Besides the dangerous stunt, good photography is also key to the trend.
That moment before it hits you.
Again, don't try this at home.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
Remind me later.
