Set iron wool on Fire 🔥with Mobile phone - Fake or Real ?

Set iron wool on Fire 🔥with Mobile phone - Fake or Real ?

I just got this video sent over Whatsapp and I ask myself,
is this for real or is this a Fake ?

Please let me know, if you have tried this already and if it will really work...
As I don´t have any iron wool here right now, I can not replicate it right now..

So who knows, please post a comment under the video.
Many thanks.

Best regards,. Stefan. .
