An Italian grandmother in Toronto known as Nonna Elda shared a very easy trick for opening a package of dried spaghetti without scissors or a knife. Instead, she held the bag vertically and gave it a good smack upon the counter. The pressure from the bottom opened the plastic seal on top.
You can just give it a good smack and there you go.
After the package was opened, Nonna Elda prepared a beautiful spaghetti dinner.
