Carlos is your best friend who's really smart and into science

One day you and Carlos were in the science lab when he haded you a red vial

"Drink it" he says

"Why" you ask but he just glares at you so you drink it after some time you shrink you were smaller than his hand

He smirks and grabs you as he holds you in his hands

"It worked.." he says as he puts you in a small jar as he takes off his shirt in front of the jar
