This blower consists of top that has the confetti loading doors, fan housing and fan blade guard, hanging bracket, the main housing body with the confetti snouts and the octagon vent bottom which is the confetti trough and the bottom air relief portion with the conical diffuser. Diversion of air flow is what helps the confetti to flow not only up and out but also out the bottom relief channel. This Vortex or Swirl is created by using a high velocity blower fan. The blower loads from the snouts or the doors on the top of the unit. This unit can be hung from a truss or positioned on a flat surface. This would be for either manual control or an external DMX unit that would be able to be controlled from a lighting console.

## Background
FIELD OF THE INVENTION
The present invention relates generally to a system and method for blowing light weight articles into air by using a fan and more particularly it relates to a system and method for blowing confetti into air by a swirl confetti blower.
BACKGROUND OF THE INVENTION
Use of lightweight materials at amusement parks, concerts, and other events like birthday, wedding, Christmas and New Year's Eve, stage shows, rock concerts, conventions, parades, circus acts etc. has long been enthusiastically enjoyed by audiences. These lightweight materials, in general, create an atmosphere of festivities and excitement for partygoers and/or spectators. Common examples of these lightweight materials include confetti, streamers, glitters, plush balls, foam shapes, etc. Confetti is often created from paper or polyvinyl film that is cut into different shapes, styles, and sizes. Confetti can also be made in a variety of different colors and shapes. Streamers are long strips of paper or polyvinyl film that are curled up into rolls. These lightweight materials, when are projected into the air, they scatter and fall creating a pleasing visual effect.
At small events, these lightweight materials can be projected by hand or a handheld projector device. But at larger events, particularly those that are held in wide areas, a specialized projector may be required, which uses a force supplying apparatus such as a gun-powder-explosive system, or compressed air from a compressed gas tanks, or a pressurized canister. Such projectors operate at pressures in the order of 600-800 p.s.i., and the cannons are usually in the order of several feet long, with a wall thickness in the order of 1⁄4 inch and composed of PVC or metal tubing. Accordingly, such systems are expensive, bulky, not environment friendly and are not safe in the hands of non-professional users.
It is apparent now that numerous innovations for confetti launching devices have been provided in the prior art that are adequate for various purposes. Furthermore, even though these innovations may be suitable for the specific purposes to which they address, accordingly, they would not be suitable for the purposes of the present invention as heretofore described. Thus a simple yet capable of blowing confetti by using a blower in a manual or automatic controlled manner is needed. Further an easy to use and safe multiple chamber confetti blowing system having low operation cost and almost no skills and training required operate system is required.
