I got this cool glass earth at the Smithsonian museum. I just made it cooler
Glass earth............................................445nm.................................................532nm
638nm.................................................405nm..................................................638nm + 532nm
Alex that's siiiiicckk! The green /red=yellow is awesome.
In the laser nerd game we call that the poor man yellow haha. Double diode build red and green.
Those types of glass are always a fun trick. Try a glass table and shine the laser through horizontally. Same effect, but the beam will shoot through the entire table.
Oh and those little glass things that have a 3d etch inside. If you unfocus your laser, you can create a hologram. Really cool stuff!
