First you need to get yourself a glass bottle something like this

Than you need a small box of matches and a rubber band to tie theme all up in one lil neat stack, then open the bottle and place theme inside, then screw on the bottle cap and then take your laser (Should be high powered of 75mW+ and using a lens would help) and then ignite the one of the matches, the first few will burn but then their will be no oxygen and you have now created a very high pressure vacuum, if you unscrew the cap a few seconds latter after a HUGE fire explosion will come out (but the bottle will not break), but if you don't do that than I suggest finding a deserted area and throwing the bottle as far as you can, it will explode and shatter into many pieces (because you waited to long and this time no fire will be coming out).
Really fun thing to try, theirs even a guy on youtube that did it (the cap was not even screwed on it was just held their by gravity) and the thing launched the bottle into the air!
