I wonder if the original model will do any more stuff like this and if she's actually into breast expansion herself or doing it for the heck of it?

Also does anyone know exactly how the effect was accomplished. I read a post on reddit from "ManIn0range", which I'll pop here for anyone interested, saying:

"It's an editing trick. She stays in the same place, is wearing a stretchy sports bra under her shirt, and has three different sizes of breast forms off-camera.
After the initial finger snap, she grabs the smallest set of props and stuffs her shirt. With the forms in place she jerks her chest upward, while continuing to sit in the same spot to minimize lower body movement. She cuts the frames between the finger snap and somewhere in the middle of the jerking motion. This gives the illusion of breasts erupting/exploding from her chest. The GIF's low framerate hides the variance of body positioning a straight cut like this normally creates.
She repeats this two more times with the increasingly larger props. The rest is acting. Rather savvy."

He sounds pretty spot on but would there be other was of accomplishing this other than photoshopping the video? Just curious and wanted to see if there were any other ideas floating around.
