Why does my ball go on top of of my box when resizing with a script?

I have this ball I need to resize only by a script. It is inside of a box. But whenever it is being resized by the script, it goes on top of the box? The ball is non-collidable and anchored. I'm betting this has something to do with ROBLOX's physics

local ball = game.Workspace.Ball
local db = true

script.Parent.Touched:Connect(function()
    if not db then
        return 
    end

    db = false

    for i = 1,25 do
        ball.Size = Vector3.new(i,i,i)
        wait(0.05)
    end

    wait(1)
    db = true

end)

The box is 5x5x5 and the ball is 1x1x1.

Why does the ball not go through the box?
