Irritable Ingestion

My project is essentially a classic boot stein revolved 360 degrees around an axis to create a cup only able to be drained by those who know how and outfitted with as many irritating, uncomfortable, and downright awful features as can be imagined. It was inspired when I needed a drink after soccer practice and all the cups in our cabinet were dirty except for my parents beer stein. I soon fell victim to a small wave of water unexpectedly washing out over my face and leaving me coughing and my older both laughing while my floor received an unanticipated cleaning. I immediately knew that this would be one of the prominent features in my prank cup. Additionally, I started by making the lip ridiculously thick. The outside is outfitted with varying sizes of triangular pieces. The large triangles prevent one from biting down fully, while the small triangles help to channel liquid down one's chin. The bottom is balanced on a precarious pedestal that will fall at the slightest nudge and is balanced only with care and patience. It's inside is filled with irregular ridges and grooves making the pouring unpredictable and further complicating the drinking process. The inside lip is also a notched surface at best uncomfortable to drink from. Their is no handle and the ridged protrusions around the cylindrical body of the cup make grasping it even more difficult, but contain the secret to successfully draining this cup of exasperation. On one of these protrusions I designed a small cylinder that indicates my hidden design feature. First orient this protrusion across from you. From the far right edge of the marked protrusion to the right edge of the protrusion on its right the boot feature is filled in and the blowback from the air bubble can easily be avoided. Every aspect of this cup was envisioned and designed for the purpose of making drinking as annoying as it can be while still making it possible to drink out of and I hope you enjoy it!
