Ice
Add a drop of something magical to water and suddenly it turns into big block of ice, just like that.
Imagine yourself adding that drop. What is it exactly? Something pretty potent, that's for sure. Now go ahead and touch the block of ice... wow, it's really cold — and only from one drop, too. Feel the burn on your finger from where you touched the ice.

When you think of ice, I want you to think of someone frozen with ice. Do you know anyone named Corey (こおり)? Anyone famous named Corey, perhaps Corey Feldman? Imagine this Corey person frozen solid with ice.
How did this happen? Was it your fault? Imagine the situation that would get Corey frozen like this.
