Laser Level
A laser level is an important tool for small and large projects. Tim Carter of AsktheBuilder.com walks you through how to use laser levels and their basic features. A regular level works well for small projects, but it has limitations due to the length of the tool. A laser level can project a line from ten to thirty feet. A laser level can also project a line around a corner. This tool is not only fun, but user friendly as well. This AsktheBuilder.com video has more details….
In reality, most low power visible lasers in the 1 to 5mw range arn’t particularly dangerous if used sensibly. A brief, accidental flash of a beam into the eye should not cause any damage. Laser levels are even less dangerous than pointers, as the beam is not a concentrated spot, rather a line which distributes the total energy of the laser over a larger area. Still, it is always best to not directly expose the eye to ANY laser beam, and if you have the goggles there’s no reason to not use them.
The laser glasses are also great for making the laser line more visible, specially in a room getting alot of sun light from windows or outside.
You can say the same thing about any number of things: Why no Kevlar vests with guns? Why no chain mail gloves packaged with circular saws? Etc. etc.
are all types of for home made lasers harmful for eyes, and why is a goggle not provided with them?
Because this tool projects the light in an arc. Some lasers create an entire circle of light by rotating the beam. Think of a high-speed lighthouse.
how does laser light go around a corner? are the photons guided by the wall?
Great video Tim! Thanks for posting.

The point of wearing the red glasses is so you can see that laser outdoors. You *need* to enhance the laser that is washed out from sunlight.
OK, everyhing you did was great but there is one problem. THOSE GOGGLES ARE FOR GREEN LASERS you want the blue ones, in fact the red ones are making the laser look brighter.
Thanks, but I am no actor like Chuck. Not too awful long ago I used to eat lunch sitting on overturned drywall buckets….. I doubt he has done that.
This guy might almost be as cool as chuck norris >.>
