Arayan:So what's the story? Did you build it? Looks very futuristic somehow, as you normally don't see lasers and vapor shooting out of a piece of fruit.
How does the vapor compare with a fog machine or other aerosol particulates. This is probably a ultrasonic humidifier, right? I don't know if you can even buy a steam one anymore:undecided:
I bet steam would make some cool effects. The laser would need to be sealed very well in that humid environment although.
Very out-of-the-box, creative, thinking.
The laser is positioned outside the "apple" and you can not see the beam because of the limited power of the pointer (3 mW of average power). The beam becomes visible only when it encounters the steam that comes out of the apple (which consists of an ultrasonic humidifier).
I bought the humidifier in a children shop, and indeed I use it when my daughter has a cough
