I'll use this to turn Gran into a little kid. How pleasant!

What's this? The degree of change depends on how diluted in water it is...?

There's even an expiration date...

Crap, he's already drinking something.

And he's super suspicious, too... A bust...?

He drank it!

He's kind to me at some fundamental level!
