Sans was helping out Gaster with some experiments about sans's magic. Sans had grown up with this magic with can cause him to use telekinesis, a glowing eye on his left and summon bone attacks. Later on, Gaster had asked sans to follow him into a room. Sans was confused. Gaster had been acting odd recently, but he goes to follow him. Sans walks into the room, but doesn't see Gaster. Sans questions "Huh... Dad? Where did you go?"
He sighs and turns around to leave. As he was about to leave, the door shut. Sans runs to the door and pulls on the handle, trying to open it, "hey! What happen?! Let me out!!"
Gaster teleports in the room looking down. Sans stops pulling on the handle and turns around to look at Gaster. Sans speaks with fear in his voice, "d-dad?! What is going on?!"
Gaster doesn't reply back. Sans looks around the room. As he looked around, he saw a machine. It was larger than sans, and Gaster for that matter. Sans points to the machine scared, "dad?! What is that?! What is going on?! Please, answer me?!"
Gaster looks at the machine, "it is for my experiment, my son".
Sans tries to back up but hits his back against the door, "what experiment dad? Do you need my help? Is that it?"
Gaster goes to the machine then looks at sans, "yes, I do need your help, my son".
Sans starts to light up a bit, "oh, in that cast... what would you like help with?"
Gaster looks and a chair that is in front of the machine, "can you go and sit in that chair? It is very important..."
Sans looks at the chair then at the machine. He sees a part of the machine is a type of laser facing to the chair. He gulps, "uh, sure thing dad."
Sans goes to sit in the chair. Once he has sat down in the chair, Gaster quickly ties sans to the chair. Sans yells, "dad! What are you doing?!"
Gaster goes to the other side of the machine and starts it up, "I am experimenting! Sans, I want to see how much magic you can hold!"
Gaster starts the machine before sans can say anything back. Sans screams in pain as the laser shoots sans and makes sans have more magic by giving him the ability to teleport and have Gaster creation that he had been working on, Gaster Blasters. A minute or three later, Gaster stops the machine and looks at the results. Sans takes a minute to breathe then speaks sounding all sleepy, "dad... what was that? And why do I feel so much magic through me right now...?"
Gaster looks at sans, "sans, how are you feeling?"
Sans gets a bit pissed off, "does it matter how I am feeling?! I am feeling fine, just drained of energy...! Can I just go home and cheek on papyrus?!"
Gaster speaks with a grin, "sans, you can stay a bit longer. I have one more thing to do."
Sans rolls his eyes, "and what may that be? Hmm?
Gaster starts the machine again taking some on the magic from sans, "to take some magic for me to study!!"
Sans tries to hold in the pain off the laser shooting him but it is too much for him. After a minute, Gaster disconnects a bottle that is filled with blue magic from the machine. Sans looks at Gaster with one eye closed, "what is that dad...? And why do I feel weak now?"
Gaster unties sans from the chair and leave the room. Sans watches Gaster leave then sighs, "What happened...? I feel so-"
Before sans could finish his sentences, he glitches out a bit. Sans's eyes widen "wow! Um, okay then... I think I might want to go back home to papyrus... I have had enough here at the lab..."
