As we wanted to add in a smoke bomb into our work, we looked on youtube and found some videos of those that we like and how-to videos.

Also, if the smoke bomb didn't work, or didn't look as good as we wanted to, we have found an alternative - coloured powder.

Health and Safety regulations for the "smoke bomb"
In our video, we are planning to use a smoke bomb. However we came across a problem that it might be illegel as it may be classed as an explosive, dangerous material. We researched the laws and regulations about explosives (http://www.hse.gov.uk/explosives/forms/exguide.pdf) and researched into actual explosives and what makes them explosives. We found that
"A primary explosive is an explosive that is extremely sensitive to stimuli such as impact, friction, heat, static electricity, or electromagnetic radiation. A relatively small amount of energy is required for initiation. As a very general rule, primary explosives are considered to be those compounds that are more sensitive than PETN. As a practical measure, primary explosives are sufficiently sensitive that they can be reliably initiated with a blow from a hammer; however, PETN can usually be initiated in this manner, so this is only a very broad guideline. Additionally, several compounds, such as nitrogen triiodide, are so sensitive that they cannot even be handled without detonating.
Primary explosives are often used in detonators or to trigger larger charges of less sensitive secondary explosives. Primary explosives are commonly used in blasting caps and percussion caps to translate a physical shock signal. In other situations, different signals such as electrical/physical shock, or in the case of laser detonation systems, light, are used to initiate an action, i.e., an explosion. A small quantity, usually milligrams, is sufficient to initiate a larger charge of explosive that is usually safer to handle.
Examples of primary high explosives are:
A secondary explosive is less sensitive than a primary explosive and require substantially more energy to be initiated. Because they are less sensitive they are usable in a wider variety of applications and are safer to handle and store. Secondary explosives are used in larger quantities in an explosive train and are usually initiated by a smaller quantity of a primary explosive.
Examples of secondary explosives include TNT and RDX.
Tertiary explosives, also called blasting agents, are so insensitive to shock that they cannot be reliably detonated by practical quantities of primary explosive, and instead require an intermediate explosive booster of secondary explosive. These are primarily used in large-scale mining and construction operations, and in terrorism.
ANFO is an example of a tertiary explosive.
Low explosives are compounds where the rate of decomposition proceeds through the material at less than the speed of sound. The decomposition is propagated by a flame front (deflagration) which travels much more slowly through the explosive material than a shock wave of a high explosive. Under normal conditions, low explosives undergo deflagration at rates that vary from a few centimeters per second to approximately 400 metres per second. It is possible for them to deflagrate very quickly, producing an effect similar to a detonation. This can happen under higher pressure or temperature, which usually occurs when ignited in a confined space.
A low explosive is usually a mixture of a combustible substance and an oxidant that decomposes rapidly (deflagration); however, they burn more slowly than a high explosive which has an extremely fast burn rate.
Low explosives are normally employed as propellants. Included in this group are gun powders and light pyrotechnics, such as flares and fireworks. "
After reading through this, we realised that smoke bombs don't count as explosives. However we do have an alternative way if we have any problems with the materials we wish to use.

Filming
We have started filming. We have filmed the part where the piece of paper is on fire that says free, it took some time to film as it wouldn't look right, or there were problems with the weather, etc... The first problem we had was the weather. There were several issues with this; at some points it was too windy and the fire would blow into plants and fly away. And the other was lighting. The difficulty we had with lighting was it was either too dark and you wouldn't be able to read what the piece of paper said properly, or it was too light and it just looked odd.
We have also started filming properly with people. We have filmed most of what we can with people, but as we want to use a smoke bomb or coloured powder, we had to research into the smoke bomb as it could be considered illegal. We have now reserached into it, so we can carry on filming.

Planning for our main task
We started writing a rough idea for our main task, to get an idea of how we want it to go, how many people we need in the video, locations, settings, etc.
The video starts off at a slow pace, to fit the pace of the music, which then speeds up after the third line. It is going to begin with a boy walking, across a field possibly.
As the third line begins, it jumps to a piece of paper on fire, and flashes images of it.
At the last line of the first verse "It plastered on a face for me."- the boy in the video will stop, look into the camera and sing the line.
As the beat speeds up, and the line "Whoa, where's your passion, where's your fire tonight?" starts, the boy starts running fast.
At the second line "Whoa, I can't believe there's nothing you're willing to hide" A girl starts running.
"Whoa, I want to believe" This line will have flashes of the two running.
"I set my body on fire so I could be free" Both stop and scream free, they throw their arms in the air and look up to the sky.
"So I could be free" x3 Clips of them running. Some in slow mo, some in black and white, all in different effects.
"Don't be told it can't be done" Flashes of fire again.
"Because the best all die young" The girl stops running.
"Yeah we all feel the same" She mimes the line, then at the end begins to run again.
"And if theres nothing left to say" The boy is running.
"Just have the guts to disagree" The boy stops running.
"Or plaster on a face for me" The boy mimes the words. You see them both running at the end of the line.
"Whoa, wheres your passion, wheres your fire tonight" They run into eachother on the 'whoa'. Then when they collide, a explosion of coloured powder rises up from where the couple are stood.
"Woah, I can't believe there's nothing you're willing to hide" They come running out of the smoke cloud, holding hands smiling/laughing.
"Woah, I want to believe, I set my body on fire so I could be free" Skip between clips of them running and clips of them lying on the floor next to eachother.
"So I could be free, yeah. So I could be free, so I could be free, yeah. Free, free. Free, so I could be free, yeah. So I could be free, so I could be free, yeah" Repeats of clips, most likely adding more in once filmed and put together.

Ancillary task 1&2 info
Here is the photo we are going to use for our cd front cover and our poster.
We've allready the front cover of the 4 insert digi pack.
For the back cover of the digi pack, we are possibly going to use a photo of the peice of paper, after it has been burned, left on the floor. The photo has been taken from further away, as if somebody has set themself free and walked away.
