    Disappointing as Mr. Hugh Johnson teaches open a bottle of champagne. In fact, he seems to fight with the bottle in a very clumsy way. According to the principle of physics which teaches that the greater the lever is less than the force required to displace a weight. Thus, the “lever” is the bottle – the great – and not the stopper – the small. Therefore, one must hold and rotate the bottle by pressing the stopper, which easily detaches, without popping, which leads to loss of the precious gas.
