Why can a laser pointer be different?
Click the laser pointer icon once to switch tools and start using the high powered laser pointer immediately. If you click twice, you will open the sub-menu of the tool, where you can choose different laser pointers, including arrows, dots and lightsabers! Move your finger around the "explain everything" canvas to point to whatever you need. To change a tool, just click the icon of another tool. Many things in life can be dangerous. We accept and take appropriate precautions to protect ourselves from these dangers. For most of these more familiar hazards, you need to be very close to the hazard before it can harm you. Examples of hazards might be cars, power tools, highly flammable materials, or knives. These hazards are very serious because they can not only harm people, but they can also kill people.

The lasers are also very good when used as laser pointers in demonstrations, but these lasers do not need to exceed 1 mW (not to mention hundreds of mW) Class 2 lasers. The green laser pointer is easier to see than the red or blue laser pointer of the same power (especially the shorter wavelength purple shade), so if it is the visible laser you want, then blue is an unnecessary A dangerous choice, and a lower power green laser is likely to be preferable. It is difficult to fairly compare the harm caused by high-power laser pointers with most other things in life that we tend to think of as dangerous. The reason is that there is nothing more like a laser because of its unique characteristics. To illustrate this point, it might be worth using some examples mentioned by others on the blog, and then discussing the differences in high-power laser pointers.
