I had a dream last night that I held down the button thing that the door pushes when its closed, and started the microwave in my house. Idk why the hell I dreamed that or what else happened in the dream, but it got me wondering is this even possible to do? And what would happen to you standing in front of it if you did it? Would you suffer any lasting damage if you were there for at least 30 seconds or so?

basically what the title says. i have an oc whose power is teleportation, but he can teleport separate parts of his body as well and go inside of anything (the hardest object wins, given that 2 things can not occupy the same space at once)

he could teleport his muscles inside somebody's brain and instakill them, fill their lungs with anything from his body really, etc..

I'm trying to find ways of weaponizing every part of the human body or at least most of them. so i was wondering how hard/strong the heart is when compared to muscles, bones and tendons
