It is tradition for students to throw the confetti into the air as soon as they graduate. The confetti cannons are often set up to shoot out pieces of paper into the air.

The tradition is believed to be started because it would be difficult for students to throw their caps in the air.

The confetti is made of small pieces of tissue paper or other fine paper and could come in a variety of colors such as white, black, and silver. They are commonly made from recycled materials like newspapers or tissue paper.

The best materials for graduations pictures are biodegradable.

The biodegradable material makes it safe for everyone and helps prevent dangerous artificial substances like plastic from flying down from the sky.   

Confetti cannons have become an easy way for people who don't know how to throw a hat into the air or does not want to throw a hat in the air after graduation and still want celebration of a lifetime.
