Flares set of a constant steady burn during their active time as a tail of colourful light follows the firework up high into the sky. There is no explosion at the maximum height of a flare but the elegant trail that climbs high into the sky is graceful. People might recognise a flare from seeing distress signals set off by ships in films or in real life. You can also buy handheld flares that emit a constant burn of colour and light. These add a dynamic creative element to photoshoots, videos, and performances.
