Please provide the geometry of the bonus jug. For example, is the cross section circular (bleach bottle) or rounded square (milk jug) and is the connection between the bottom of the jug and the wall rounded.

The bonus jug will be a plastic milk or juice jug provided by the local event supervisor and will be what is available locally. It is recommended to use a jug that is squared on the bottom and has 4 sides, not a rounded jug. If there are more than one playing fields are a competition, the jugs must be identical.
