Question

What would happen if you took a really strong metal box and you started teleporting in hundreds and hundreds of small cotton balls until there is no space left and when you are 100% sure there is no more space left u teleport in a small metal ball.
What would happen to the metal box?Would it explode?Or what would happen to it?

Ps:the box was created as just one pice so it doesn’t have any lid or anything.And I know teleportation is still not possible.

Answer 1

It's your story. You invented teleportation to make an exciting plot. Now go ahead and finish the story, by making up the thrilling climax.

Answer 2

It will not explode since the mass of the cotton balls is so low but rather will most likely break the lock and hinges and come out.
