asctuall not all fog machines use dry ice some use fog juice (can't tell you exactly what is, but it is its name) to make the fog


In most commercial fog machines, triethylene glycol mixed with water is usually used.

They made 'laser art' at the Science Centre in the city..

They turned them all on and made a 'mirrorbox' with mirrors at the exact angles, which reflected all the beams onto the black wall into different shapes and stuff.. Looked pretty cool, but lots of laser pointers are needed. Just dont aim them at your eyes  :o

The best way to do it would be to make a glowpad/window out of plexi with a bit of dust/imperfections made IN the plexi.  These would make the path show up. Then add mirrors at the edges and you get shapes.

if Im not mistaken. Firing a white light into a prism makes a multitude of colors. I wonder what a laser would look like in a prism?

the laser light is unaffected


Prism breaks up white light into it's component wavelengths.
Laser only has one wavelenth, it is only one color, therefore should be unaffected.

To get the lazer to show up,  sandpaper the plexy lightly with some high grit paper.  Wouldnt it still allow vision, but make the lazer more visable?
