  • Can this be shot into an audience ? Or is it bad for the eyes. If so how can I make one that aint

  • @justindustries I have shot these over the heads of a crowd and, depending on the power of your laser, the individual beam strenght is below the 1mW regulations for beams into a crowd. The important thing to remember is that the strongest beams will be near the center, so make sure that is over thier heads. Good luck.

  • @Starcross42 Thanks ! Ok and besides the regulations if I'd shoot a class 2 laser into a crowd diffracted can that possibly harm anyone. Do you have any tips on websites to buy all the diffraction gradings and stuff.. I'm a total noob with lasers but it looks fun to make one, and it would safe ma allot of money :)..

  • @justindustries If you go to altmanscience (dot) com you can order diffraction gratings from me.

    You can also order an ebook showing you how to build all these effects.

  • What is the max output on your laser?

  • @theben00233 20mW

  • What kind of smoke is this guy blowing into the laser. I love my legos, lol.

  • @FaithBane I get my motors from American Science and Surplus. Give them a try.

  • @Starcross42 Would servos work? if so, they are extremely cheap on ebay.
