Random Association

Random Word technique, the most basic and obviously creative technique where you use a random word (hence the name!) to generate new ideas. By getting a random word as a prompt and forcing yourself to use it to solve your problem you are practically guaranteed to attack the problem from a different direction to normal. You take a word from a random word generator, extract its underlying principles and then apply them to your problem to see how they can help. The skill is stopping your mind from:
(a) thinking this is silly and 
(b) directly using the actual principles behind the word to your problem without changing them to ones which                             are easier to apply.

In the class, we need to think a ways to stop people from smoking by using random word technique. Related the answer with traffic light.

there are 4 words can be taken from traffic light.
-sign
-color
-metal 
-dirty.

Sign
Put sign on the cigarette, MIND YOU LIVE. It will make people think. Mostly all of the smokers know the danger of smoking but they just ignore it. So, by putting this sign, it will make them beware of the danger of smoking.

Color
Put some colors to indicate the levels of danger on the cigarette. Its really useful. Green to show safe, Yellow to show be careful and Red to extremely dangerous. 

Metal. 
Put metal such as silver at the cigarette butt. Not just the price will increase but the weigh will increase too. Moreover, after a few minutes smoking, the silver will absorb the heat and become hot. Of course no one want to hold a hot thing. 

Dirty
Put some dirty chemical substances in the cigarette.Make sure that the substances can last for a long time. The mouth of the smokers will surely stinks.
