Incredibly easy and very colorful!

 

Start with the empty cylinder, and place it on a tray. Show a pretty feather flower, and place it into the cyclinder. When you lift the cyclinder, the single flower has magically transformed into a full bouquet of colorful flowers! 

 

This flashy and impressive trick is extremely easy to perform, and shows up well at a distance. It can be performed at close range as well, or even surrounded! Best of all, it sets up quickly and easily.
