Zero-gravity Coffee Cup

Here is a zero-gravity like coffee cup. When you want to have a cup of coffee, it can be placed vertically, but when not in use, it can stay balanced at a perfect angle.
A coffee cup may refer to a type of container from which coffee is consumed. Coffee cups are typically made of glazed ceramic, and have a single handle, allowing for portability while still hot. Ceramic construction allows to be drunk while hot, providing insulation to the beverage, and quickly washed with cold water without fear of breakage, compared to typical vessels made of glass.
