EVER WONDERED HOW … A MISSILE CAKE FIRES?

As some of you may know, the management team are over in China selecting the new goods for the range for the 2018 Bonfire Night season.

Here is a little video which shows a missile cake (barrage) in slow motion going through the different patterns of burning and bursting into the air as. The sound close up is a strange one but you can hear the breaks as they hit the air. A fascinating insight into how fireworks work.

Slow Motion Fireworks, 210 frames per second, cooooool

Whilst the human mind working together with the optic nerve can distinguish 10-12 separate images per second, these days most T.V and film you watch would be filmed at 25 frames per second to give the illusion of seamless images. Increase the frame rate and hey presto, slower video.

This footage was filmed at a fast 210 frames per second and gives our visionary senses time to study each image separately, mull it over in our heads and move on to the next.

At these film speeds, fireworks especially, give us a new insight as to what happens at each stage of the pyrotechnics “show” from the gradual lift to the blossoming of the burst.

Watch and enjoy as Crossett’s burst out at almost eight and a half times slower than you would usually watch them at.

Slow Motion Sparkler Video

You should always be particularly vigilant if you are using sparklers because although they are a truly beautiful thing, like all fireworks they must be handled with care.

As shown in the above video, whilst the film is in slow motion, you can clearly see that a naked flame takes a long while to heat up the chemicals in the sparkler before it erupts.

There have been a number of tests carried out over the years and sparklers are able to reach temperatures of up to 1600 degrees centigrade or 3000 degrees Fahrenheit which is around the same temperature as a meteor entering earth’s atmosphere or as a blow torch

Sparklers should never be used by children under five and all other ages should be only under strict supervision.

Here are a few tips to help you to use sparklers safely:

• Store in a cool dry place
• Light one sparkler at a time
• Wear gloves
• Do not allow children with loose, floaty clothing to use sparklers – they can catch the clothing and set it alight
• Never give to under 5’s
• In an emergency, cool the burn for around 10 minutes and cover with cling film and get advice from a GP or A&E Department

Sparklers are used in a number of different circumstances nowadays so if you are attending a wedding or a bonfire display, bear the recommendations in mind and keep sparkler safe.
