I'll have to agree, the gobstopper was probably the least impressive. The giant golden egg geese were mighty impressive (and he tamed them and set them for production), and he bred a gaggle of them for mass production of golden chocolate eggs to shrink down in another station of the factory (if I remember him stating so; that, or wrapping them), not to forget, the soda that gave you the ability of flight appealed to me the most. Although were the fans bowing in or out of the room? If out, then it was venting out chemicals that could get hazardous if too dense, and if blowing in, then it was containing gases, but not enough power was being delivered to keep those who have consumed too much from going out. Even if such hazards were a possibility (in this case, it was accidental), why weren't there any protective grates or anything to prevent even an Oompa Loompa from getting turned into diced carrot?This comes to mind.
