I want to get a 5mW blue laser pointer, but I know laser pointers can be dangerous so I need to know if there is anything I should know before I get it. Do I need any special goggles or glasses to look at the beam?
That's an old wife's tale. Lightening strikes the same places time and again.
look up the plumbing pipe sizes for china and compare them to us sizes.i tried to find it for you but no luck ,but from what i did see i think it will work if its different then i'm sure there is something to convert it to us sizes.but it looks the same from what i've seen
I started riding when I was 16. My mother helped me with the loan on my first bike. Like any mother, she didn't like the idea. Life is dangerous in general. You can get badly injured playing most sports. You reduce risk on a motorcycle by: Wearing proper safety equipment. Going through a training school. Acting mature (many accidents are caused by the rider showing off - wheelies etc) Ramping up. Take small rides in low traffic areas until you are comfortable to go farther. Understand how to spot trouble before it happens. This goes beyond basic defensive driving. You should be able to look down a road and predict how traffic is going to react long before it does. I also recommend eliminating rules of the road mindset. By that I mean, forget what the rules are and how cars are supposed to behave according to road laws they don't. Forget laws and think of it more like navigating a small boat down a dynamic stream with moving obstacles. You don't expect objects in a river to follow patterns and laws, you shouldn't expect cars to follow laws and patterns.I see no reason why you can start riding at 16. I was on a minibike at 5. A dirtbike at 12. A streetbike at 16. At some point, you will be tempted to test the bike with speed or manuvering. You will be tempted to show off to friends and or girls. You will be tempted to give your friends rides on the back. You will be tempted to do something out of place like go off road or something. Avoid these temptations as a new rider, as they are how new riders tend to screw up.
