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.
A unilateral contract is a legal agreement in which one party to the contract promises to take a specific action if the other party proactively takes, or refrains from taking, a specific action. For example, one party may contract to pay the other $100 if the other party walks one mile or refrains from walking one mile for a period of one week.
