I have observed that certain materials can drive fluids into themselves and push their own molecules apart, thus inflating itself. When, I try to reason, I'm not quite successful. Even if there is surface tension or under atm pressure, extension of intermol. distance is departure from equilibrium, which I'm not sure is supposed to happen. If it is already internally stressed, then it must also eat up surrounding air, but it does that only with water.
