A simple drinking game which is usually best left for later in the night when everyone is a bit drunk already. It is played using:-
A large potato
A group of people
Alcoholic drinks
Everyone stands in a large, closely packed group with one designated 'potato tosser' standing outside the main group. Everyone except the tosser must hold their drink. The tosser then launches the potato with the aim of it landing somewhere among the group. Anyone within the group who looks up after the potato has been thrown must consume their entire drink. Anyone who moves after potato has been thrown must consume their entire drink. The person that the potato hits must drink their entire drink and then they become the potato tosser.
An oval-shaped object used in physics diagrams to represent an arbitrary massive continuum undergoing rigid-body motion. Called such because often the drawn object resembles a potato
In Figure 1, for any two points A and B located on the potato, the relative position of point B with respect to point A is given by the vector (X_B - X_A) in the reference configuration and equivalently by the vector (X'_B - X'_A) in the moving configuration. The rigid body assumption states that the only changes in configuration the potato is allowed to undergo are ones in which the magnitude of the relative position vector (X'_B - X'_A) stays the same over the course of the transformation.
