It works very well and the balloon explodes right after pressing the button on the remote. And it's
not necessary to put flash cotton on the top as they explain on the video.
BUT there are
some other big issues, that they haven't considered. First of all there is a long black thing with
the wire sticking out of the top of the white balloon stick. So everybody can see that it's not a
normal stick. Well, you can just start with the balloon on the stick, you might think. Yes, but
after the balloon explodes then everybody will see it then. And another thing. The wire will glow
some seconds AFTER the balloon has exploded, so again will everybody see a very bright red light
coming from the stick, since all the attention is where the balloon exploded.
I would have
given this one star if not I was clever enough to make some changes. I have colored the black thing
white so now you won't notice it. But they can still see the bright red light coming from the wire
on the stick. So I filled the balloon with silver confetti and now when the ballon explodes there
will be confetti to cover the light :-)
For the effect with my changes I give it 5 stars,
but because I had to come up with these changes I give it 3 stars. If I hadn't found a solution I
would never had used it...
