    FAIL THREAD!!!!

    Well I just happened to study sustainability for a couple years in University and I can say that hemp makes excellent toilet paper! :D In addition hemp oil can produce plastics of as high a quality as fossil fuel oil. I know of a few products that are made of hemp plastic. Hemp is a fantastic...

    FAIL THREAD!!!!

    The one thing to keep in mind related to the amount of additional CO2 released by humans is how fast the carbon sinks (trees) and other photosynthetic organisms can strip the carbon from all the extra CO2 produced because of humankind and then release oxygen in return. I know it seems cliche to...

    Dave, that is interesting what you wrote about the global warming bringing an ice age, and the...

    Dave, that is interesting what you wrote about the global warming bringing an ice age, and the underlying processes that will / could cause this. Do you teach any Sciences at your University? You are a man of many talents and wise on many different subjects, and I always look forward to...

    Seeking Advice from experinced Fourm sellers and buyers

    Ryan, I think you are a good person and I would love to be a customer of yours in the future. One thing I think about related to the forums is that it is a very generous privilege that the forums are here for some of us to be able to make a little money here and there. They do not owe us...

    Uranium Glass Tubing

    I apologize, I didn't intend to sound like a goof over exaggerating the danger of Uranium glass. I admit, I didn't know it was so low concentration. As for pure DU though, I think it is good to know the truth about depleted Uranium munitions. I always remember that everyone in the military is...

    FAIL THREAD!!!!

    That is a really good point! I totally agree. I always found it weird that people believe that government made up global warming as a conspiracy to charge carbon taxes and control us. The fact is as you say, they do not want you to consume less and use less oil. I really do not believe that...

    FAIL THREAD!!!!

    Good point there. I guess I shouldn't have worded it so "black and white" so to speak. While it is hard for some to make it out of poverty, many can your right. We have the same kind of welfare abuse here as well. I didn't mean to criticize the U.S. in any way I am American as well and I love it...

    Why can laser pointers be so much cheaper than the diode alone?

    Don't forget green lasers don't use a direct green diode. It is called DPSS or diode pumped solid state and uses an IR diode to pump into a frequency doubling crystal to produce the green light. I am by no means an expert and am still new, but I would recommend doing a lot more reading and learn...

    Uranium Glass Tubing

    Exactly. Certain things that have low amounts of radioactivity that are generally of low concern to the body externally such as depleted uranium are VERY bad if they are aerosolized or in particulate form where they can be deposited in the lungs and stay there permanently. The low amounts of...

    FAIL THREAD!!!!

    Well hopefully the queen doesn't have that much power here in Canada... Yeah it is true that Canada has less than the population of all of California! I know this is kind of a semi controversial statement, but the difference in violence and crime between Canada and the U.S. partly has to do...

    Dubstep or Drum n Bass - if you like it post a song!

    That sounds great. Once you go to a big sound like that you can't go back. :D Here's a clip from the Shambhala festival near Nelson B.C. Canada. It's held on a farm that borders the forest and there are 6 or so stages all with different themes. This one is called the village and it is like the...

    Saw my first beam today, didn't want to

    I agree. I feel badly for the fact that your parents don't believe you on this. What if it was something worse, your parents should always trust you when it comes to abuse / sexual abuse and this situation practically falls in that category. Very rarely do kids / young adults make up things of...

    Actually, I think that is a good question! :)

    Dubstep or Drum n Bass - if you like it post a song!

    Hi Ped, Yeah that was cool man thanks I like those! I actually have some late 80's and very early 90's house music that sounds a bit like that. What era is the last track you posted with the nice bass sweep? I like that kind of house as well even though I am mostly a drum n bass guy. I'll...

    How do I build a laser?

    Hi Pat, I did a review of the Survival Laser 445nm blue, and I use it at the lower power mode as well using the single 18650. There are some pictures in my review of the 100mW- 300mW low power mode. Link below...
