BUT ....
I implore each of this amount of Nutella opens urgently to do it in closed rooms! And I mean really closed! A tilted window alone does not preserve from harm. If a cat flap is present or ventilation shafts nailed them with boards necessarily before opening the Nutella bucket.
All the smile now just tired, be warned! A good friend of mine has not heeded my advice and the thing opened on its terrace. Within a very short time only one hand and a shoe from him under a gigantic pile was seen chirping and Trippel Squirrels. The emergency has meant that my buddy has only survived because the squirrels had the bucket eaten as soon empty and were gone that resuscitation (which is actually only consisted of the removal of two squirrels from the trachea with subsequent cardiac / pulmonary resuscitation) could be timely.
So, ye may be warned on that it does not say afterwards: "Where all at once come the Eichhörb .... ARGH !!!"
