What color laser will pop a balloon?
The Science: The Black Balloon pops because the black colour absorbs the heat from the laser, causing the balloon to ‘burn’ a hole into it. The White Balloon does not pop as white is not a colour which absorbs heat as easily.
Are 5mW laser pointers illegal?
Those handheld green lasers pointers may not be as harmless as you thought. The Code of Federal Regulations in the United States limits commercial class IIIa lasers to 5 milliwatts (mW). And yes, lasers above 5 mW are commercially available in the United States, but it is illegal to market them as Class IIIa devices.
Is a 5mW laser powerful?
In a nutshell, 5mW lasers are very powerful and can cause severe damage if not handled properly. They could cause permanent damage to your eyes and burn certain materials.
Can you see the beam of a 5mW green laser pointer?
With a 5mW green laser pointer, Rayleigh scattering is pretty easy to see.
Can you pop a balloon with a green laser?
As seen in the vid below, it took a while for the 750-1,000mW laser, fired through a focusing lens, to pop each balloon, but it eventually did the trick. The green beam left a trail of red balloon fragments in its wake. Fortunately it wasn’t powerful enough to penetrate the far wall.
What do Green lasers do?
Green lasers are used by astronomers to point out celestial bodies to other people. This type of laser is more effective for astronomical purposes than other colored lasers because of its power. The power of green laser pointers varies, but even weak lasers are more effective for astronomy than red or blue lasers.

Is 5mW laser always visible?
For a list of other laser sights, see Laser. The 5mW Laser is an attachment featured in Call of Duty: Modern Warfare. However, the laser beam is visible while it is providing benefit, which is when the player is not aiming down sight or sprinting.
What class is 5mW laser?
class 3R
Laser systems with an output power between 1mW and 5mW are rated class 3R, between 5mW and 500mW are rated class 3B. Every laser with more than 500mW accessible radiation is specified class 4. Even class 4 lasers are safe for audience scanning, if the MPE is not exceeded in the audience area.
Can 5MW laser blind you?
They won’t burn you. They won’t cause permanent eye damage. Of course, in a real-world incident, laser light entering the eye would likely last for less than one second, as people naturally look away from bright things and close their eyes, so there is no real danger of direct damage.
