This is a comedy prop, like your Breakaway Wands and Breakaway Fans, Drooping Flower and other similar gag props.
The apparatus we supply comprises of a long stemmed rose. Several members of the audience are invited to smell the rose. However when one particular member smells it, the rose just drops off the stem.
The performer replaces this on the stem, and the flower is back in place. He repeats the process, and again the flower drops off whenever the performer so wishes.
Or if you wish to be politically correct, the rose would stay in place when any members of your audience smelt it, but drop off every time you tried !
A simple item, very easy to use, and supplied with instructions and ideas for your use. Recommended for Kid Show and comedy show performers.
