プリンス・ラパートの滴
1. Prince Rupert's DropPrince Rupert's Drops (also known as Rupert's Balls or Dutch tears) are a glass curiosity created by dripping hot molten glass into cold water. The glass cools into a tadpole-shaped droplet with a long, thin tail. The water rapidly cools the molten glass on the outside of the drop, while the inner portion of the drop remains significantly hotter. When the glass on the inside eventually cools, it contracts inside the already-solid outer part.
