In this tutorial, I will teach you how to make an Origami Flapping Bird (really flaps!) using a regular sheet of printer paper. If you have any origami or square paper, that would be ideal to use. Making the Origami Flapping Bird is very similar to making the Origami Crane, yet with fewer folds.
invitation for bid (IFB) A part of the sealed bid process. Companies or government organizations give in-depth specifications for projects and invite contractors to bid their proposals for various projects. The sealed bids are opened at the predetermined time and recorded. A contract is awarded to the best bid.
Definition of Unilateral Contract: Contract in which only one party is required to do something. Explanation of Unilateral Contract: A unilateral contract is an agreement in which one party performs a specific act, typically in exchange for money. Unlike a bilateral contract, a unilateral contract only contains a promisor. For example, in a nonexclusive real estate listing, an agent does not enter into an agreement with a seller unless he or she finds an appropriate buyer first.
