So this is what I was talking about, while molding, it's such a great experience, because we have freedom of like walking, or moving my hand or, moving around in the space, but the moment this becomes solid, when you cannot move even an inch, because this is plaster of Paris, so the moment you pour it it's like liquid; but after 20 minutes, it's almost like a hard stone.
所以，这就是我制模时候讲的话。 这种体验非常之棒， 因为我们拥有自由如走路， 自由地挥挥手。 但是在一瞬间这些都凝固了， 你一动也不能动， 因为他是熟石灰，这一刻它流动自如， 20分钟后，他就硬如磐石了。
