If by chance one day you decide to dine light do as I do: go to a supermarket.
Once inside you try to buy something that maybe you have already purchased and which do not suck too. Well, once identified, try to buy something with which combine all such bread or breadsticks.
Go to the checkout and return to your hotel, all to enjoy your much desired dinner.
If you have done so, you have done the math without the host, and you will understand looking at the picture below.

That’s right … in these two boxes there are not tabs and therefore how to do? Carefully follow my tutorial and you will find out.
Take the towel of the hotel, and place it on what is as sharp as you find (here I use the edge of the wooden table). Subsequently pressed slightly the center of the jar to put pressure inside, then hit with sharp blows until the mixture inside bait.

Well at this point for a short period so eat it, in order to create a vacuum at the center and then with everything you possess (I washed the house keys and then used as opener) widened the gap even more.

Obviously this thing function better if you bought breadsticks or bread as long in this picture.
Well at this point when you realized how you fell down … do as I do: Please ask your hotel where is the nearest restaurant, and it’s good.
