Inverted Wine Glass

Wine galsses are pretty but the majority of the weight is located above the ground, where it is more prone to toppling due to its high center of gravity, spilling your wine/champagne/sparkling wine/Pepsi all over yourself or the table on which it sits. To conteract this problem (or avoid it altogether) I've designed a cup whose center of gravity is as low as possible.

The beverage itself is contained in a slighly elongated sphere, of plastic or glass (though preferably plastic) which has the same volume as a glass of wine. At the top of the sphere is a small circluar opening 1'' (2.5 cm) across. This ajoins the cup part, the sphere, to the stem of the cup which sits on top of the sphere. The stem gradually narrows in diameter from the 2 1/2 cm to half a centimeter (less than 1/4 inch) at the midway point of the stem, and then widens and flares at the mouth to 2"(5 cm). The entire stem is 3'' (7 1/2 cm) and the height of the sphere is also 3".

At one side of the mouth is a tiny drainage spout like those on pitchers and coffee pots for easy drinking. On the side of the stem opposite this spout are two holes whith a sliding plastic cover over both of them. When the drinker is not drinking, the cover plugs both holes, and when the drinker is about to drink, he/she slides the 'latch' off to the side of the holes allowing for easier drinking.

No matter how far one pushes the tip of the cup to one side, it will always spring back up to an erect postition, gently swaying to and fro as its contents make tiny waves. The contents cannot be spilled when the holes are plugged, without trying very hard. Even blancing the cup on its mouth with the beverage inside could prove an inefficient way to empty it, as the narrow stem creates a vacuum. If it falls off the table, the weight of the liquid rights the cup in midair and when it hits the ground, the plastic sphere will absorb the impact and it will sway wildly then right itself again. It is because of its durability and weight that it can actually be thrown across rooms to fellow beverage drinkers. This makes beverage-drinking get-togethers more interesting too as everyone's boring sessile wine glass would be replaced by bobbing, rocking, and spinning (yes, you can spin them too) cups.

They can be made of glass as well and be etched and formed just as poshly as current wine glasses, if the buyer so desires and can be made in any size.
