i'm sure senior briggs is just kidding and not making any assumptions here. so just some harmlessl humour and that's all
so... there are a number od DC/DC converters that can easily accept 12v as input and have 6v as output. or you can wire a second battery just for the use of the laser projector coupled with a dc/dc cobverter. you can even build your own d/dc converter using an LM 350, or LM 337 or LT 1084 IC. schematics can be found all over google and the circuit is pretty simple (even i can do it and i am no electronics guru)
i suppose a laser crab will be pretty dim and worthless of the effort. i suggest you get some cheap galvos, a 445 diode, a flexmod, a 405-g-2 lens and a pair of anamoprhic prisms and make yourself a nice powerfull blue projector. or you can get a ready made 1w module (there are a few on ebay or even better, some PL memmebrs already have these available)
then, you will only have to worry about the laser output pointing towards the ceiling of the venue and not into the faces of people
just my 2p
