Over 227 million people around the world speak Bengali.
It’s not just a language - it’s emotion, culture, and a powerful bridge to a vast audience.

4:06 "This tray makes your drink unspilleable"
the moment of silence after he said how much you "jerk" felt like he was contemplating his choice of words :)

J'étais en train de m'endormir devant mon projecteur et je me réveille voyant que RUclips s'est laissé aller a des recommandations comme ta vidéo... Résultats je regarde curieuse et ravie du sens de l'humour.

Laughing at you eating the metal. Reminds me of my elementary years in Tonga when the fad was tearing soda cans into quarter size square pieces and chewing and flipping them around in your mouth to hear the pops like gum. We were ahead of our times 😄
