Where can I buy a laser with a path that you can see
You can't. Unless it goes through water or something then you can't see it.
laser, as in a laser pointer? If so, go to walmart or a general store, lol.
A laser need something to reflect off of, like smoke, to see the beam.
Office Depot.... Staples... Petco.... Places like that.
if you want a laser that goes 5 miles go to oceon city only 20 dollars lol
