I will not fly / Cork

I will not fly

when we press a cork in into a thermos full of boiling water, the cork will be lifted by the water vapor and fall on the ground. This is because the usual cork is in a circular truncated cone shape so that when we press the cork into the thermos, the pressure from vapor on the cork bottom is relatively uniform and thus the whole cork is ejected. The design of “I will not fly”, a change in the external form, cut off a part of the cork in order to form nonuniform of the vapor pressure on it. In this way, one side of the cork will be lifted slightly first through which the vapor escapes and then, the cork fall back by the weight.
