its simple but requires lots of patience ...
follow these steps>>>>
1 get a CD or DVD
2 open it...actually a CD or DVd is made up of two circular plates joined together
with a silica sheet between them
3 remove this silica sheet ...be careful...do not inhale it
4 take some phosphorous power ...you can take it from match sticks ...or you can use the black power from some diwali crackers
5 take some wood sprite or the rubber glue...and mix it with the power to make a paste
6 put this paste in place of silica sheet and put the two circular plates back
7 they will stick by there own if you are using rubber glue ...else you need to put some fevicol on the edges
8 keep it to dry ...
9 gift it to some friend

10 he/she will put it in CD/DVD drive and them ....BOOM!!!

actually CD or DVD drive has a laser that reads the data but in our case it will ignite the paste ...
now some geeks wud ask how will it burn with out oxygen supply...then my dear geek friend ...the paste contains air bubbles ....if you still dont believe me then try it on your own pC...
