Flower Tray, 4 Time

The Magician displays an empty tray. He takes some coloured tissue paper and tears it into small pieces, which are placed on the Tray. 

When he wishes, the pieces of paper on the 'Tray' change to a bunch of different coloured flowers.
After this he repeats the effect, producing a second bunch, perhaps of a different colour.

You can also produce the flowers on the empty tray without using the paper pieces or even produce silks, ribbons, latex production goods, sponge balls etc. instead of spring flowers.
