I've been playing around some with laser and ferrocell. When i directed my aim at a copper plate i got this nice arch of light, and as we know we can get a similar effect from a ferrocell.
Than decided to put them together and got nice reflection of it which looks like a bright star. the steeper angle we go, the "brighter" the star is. (only made a video since it's to hard to make a steady picture with out laser holding equipments xD) With the ferrocell lying on the copper plate: With the ferrocell above the copper plate(the ferrocell inside the cell holding device):
All i have used is a laser, a copper plate and a ferrocell. First the laser directly at the copper plate which gave the arch of light, than i put a ferrocell on the copper which gave the star, than we had to lift the ferrocell above the copper to make the star more bright.
