Your director says you couldn't possibly because you'd scare the audience. You decide not to mention that a well timed bang might actually jolt the audience awake after drifting off in the third hour of the second half, but you decide not to for fear of being yelled at... again.
If you have experienced this problem then we have the perfect product for you - handheld confetti cannons.
Available in white, white and silver mix and multi-coloured the hand held confetti cannons are perfectly safe to use and pose no danger. Handheld cannons are single use cannons pre-filled with confetti or streamers. The lowest part contains a pressurized nitrogen cartridge. Easily twist the lowest part of the cannon to the left and the confetti or streamers will be launched into the air.
Prices start at just £3.78 + VAT for a 28cm cannon - so even the price shouldn't be a problem!
