Need some help with explosive jar part

[skubaben]

Okay i see now i am not the only one with this problem. Question is. Is it a bug or something we do wrong? Its looks really easy on every video. So i cant Imagen that its suppose to be hard to place.

I started to love this game more and more, So i cant give up here just annoying i spent hours trying this. And its not like am stuck at a puzzle. Should i start a new game hope for better results? Or is it something thing els that reason that i cant put the jar down? It is full with explosives.
