Surprise your guests or the mummy to be with our blue gender reveal smoke cannon. Announce your new baby boy with a bang - this gender reveal paint cannon will let out a puff of coloured blue smoke with a scattering of blue confetti to make your gender reveal extra special. The pink and navy packaging is gender neutral so family and friends will not know what colour will come cascading out the cannon, revealing a blue confetti explosion. There is a blue sticker on the cannon to identify the blue confetti inside. Remove the sticker before your guests arrive to keep the gender a mystery! Each pack contains 1 boy blue gender reveal cannon measuring 30cm (H) by 4.5cm (W) - for use outside only. Paint may stain. Once opened the smoke will last for an estimated 60 seconds in total.
