Hi,

We have made a sort of laser labyrinth, with adjustable mirrors and  
smoke. The smoke is used in order for the users to see the laser, the  
mirrors are used to direct the laser throgh the labyrint. But we’ve  
hit a couple of snags that have stopped the development. The mirrors  
get covered with residue form the smoke, so I had to wipe them off  
every day or so. Even though we mounted an extraction tube on the  
table, so the smoke would be sucked out.  I know there’s different  
kinds of theatrical smoke, but I’ve tried a few and they all seem to  
have the same problem.

Any thoughts?

Best regards,

Mvh. Jon Haavie
