I don't think... short of radioisotopes that you could have picked a more dangerous project... AND a First one Yet... I just looked at the calendar and we're not even close to April First. 100 mW of IR power is enough to cause blindness and the IR "Beam" is invisible. 25W focused is enough to cut thin sheet metal.
THIS IS EXTREMELY DANGEROUS AND ILLEGAL IN A BUNCH OF DIFFERENT PLACES...
