my weired invention

I made a weired invention first,i made a idea,then i did a dumpling first i made a small pie,then,i rolled for a bigger one with a bread roller to make it flat!
i put vegeatables,tofu and other edible stuffs i roll again,it went inside then i put more edible stuffs,i warpped it!i did not close it a lot but it did not have any thing falling,that is weired right,i have some anwsers to it:
it is too sticky,
it is too much that there is a small amout of hole for it to come,
does not fit thorought hole.
also i made a bun with nothin inside like a submarine,mabey if you may like it email me at :scott.qi718@gmail.com!
