Many countries have the custom of launching fireworks. Many people have been seriously injured that led to loss of sight. All pyrotechnically objects have in themselves destructive potential, and not everyone knows how to protect him/herself from them.
The solution to these problems is a confetti launcher, like a cold torch.
The confetti launcher is in fact a one use plastic tube with confetti. With a simple procedure, from this tube for one use will flow waves of confetti, on distance.
