  1. If I had some type of triangletion system and I on one of the systems I have a laser that hit the target. Then I have a modle rocket equiped with four photodiodes that interceps the target in the triangletion zone. Would this work?

  2. I did not mean sterilize agar and petri dishes in the same pot, I was wondering how long a steril petri dish can stay in open air before it is not steril anymore? Also, does anyone know a "cheap homemade" way to keep steril glass petri dishes steril? I was think jaring them or something like that.

  3. That's to Bad,

     

    I know a pressure cookers can sterilize agar, but can pressure cookers sterilize glass petri dishes. If they can would it be better to sterilize the agar and the petri in two pressure cookers instead of letting one sit wile the other is cooking, or is doesn't matter?

  4. I think we need to define branch. If you take a terminal shoot and root it, it becomes a trunk and has no branches (i.e., a stick) and will not fruit. If you take a primary branch from a tree that only fruits on tertiary branches and manage to root that, then asuming that branch had secondary and tertiary branches (and used to fruit), then once it has rooted you would have a trunk with only primary and secondary branches which would not fruit until it had developed the next set of branches.

     

    Trees do respond to the number of ramifications they have. It affects the distribution of auxins and other hormones which determines which parts of the tree are which (i.e. which is a trunk, a primary branch, a secondary branch, a leading shoot etc..), how each part grows and the likelihood of fruiting. Taking cuttings affects the distribution of these hormones.

     

    This is why a cutting even one taken from the finest twig, furthest away from the trunk after many ramifications, once rooted will become a trunk and will not bear fruit, but will take on the physical and physiological characteristics of a trunk and begin to form primary branches. It really is amazing if you think about it.

     

    Anyway, things are a bit more complicated with avocado as, to guarantee fruit, you need to have two different varieties growing in proximity. See here.

     

     

    If you grafted more branches could to speed this up?

  5. If you use rooting hormone to start a root from a avocado branch will it make fruit as soon as it gets big enough or do you still have to wait four year until it starts make food?

  6. Here some for text.com:

     

    (first one does not work of course)

     

    SMOKE BOMBS

     

    I don't know if this one works, but it might. Mix six parts Epsom

    Salts and three parts sugar over a low flame. When it turns into a gel,

    pour it into a container and stick a few matches in as fuses. Four pounds

    is supposed to fill a city block.

     

    4 parts sugar to 6 parts potassium nitrate (SALT PETER). Heat over low

    flame untill it melts. Stir well. Pour it into a container and stick in a

    few matches as fuses. One lb fills a block nicely with thick white smoke.

     

    HTH smoke bomb: Using HTH pool chlorine (2 parts) and non-silicone

    brake fluid (3 parts) makes one hell of a smoke bomb. When you add these two

    together, it gives off really thick smoke.

     

     

     

     

     

    SMOKE SCREENS

     

    Here is a somewhat explosive composition uses by the Germans in WWII for

    black smoke:

     

    Hexachloroethane - 60%

    Anthracene - 20%

    Magnesium(powder)- 20%

     

    Brown Smoke:

     

    Pitch - 29.2%

    Pottasium Nitrate- 47.4%

    Borax - 10.6%

    Calcium Carbonate- 4.9%

    Sand - 4.0%

    Sulpher - 3.9%

     

    Note: You may substite pitch by soaking liquid tar in sawdust. This has better

    effect.

     

    Grey Smoke:

     

    A:

    Hexachloroethane - 50%

    Zinc Powder - 25%

    Zinc Oxide - 10%

    Pottasium Nitrate- 10%

    Colophony Resin - 5%

     

    B:

    Hexachloroethane - 45.5%

    Zinc Oxide - 45.5%

    Calcium Silicide - 9.0%

     

    Note: Because of the high vapor presure of HC, HC smokes must(be sealed in

    and artight container. Also the Zinc Powder one may react with water so

    be carefull.

     

    White Smoke:

     

    Potassium Chlorate- 20%

    Ammonium Chloride - 50%

    Naphthalene - 20%

    Charcoal - 10%

     

    Pottasium Nitrate - 48.5%

    Sulpher - 48.5%

    Realgar - 3.0%

     

    Pottasium Nitrate - 50%

    Sugar - 50%

     

    Yellow Smoke:

     

    Potassium Nitrate - 25%

    Sulpher - 16%

    Realgar - 59%

     

    Other Black Smoke:

     

    This one make the most beautifull black smoke but is expensive.

     

    Potassium Perchlorate - 44%

    Antimony Trisulphide - 24%

    Naphthalene - 26%

    Soluble Glutinous Rice Starch - 6%

     

    Potassium Perchlorate - 56%

    Sulpher - 11%

    Anthracene - 33%

     

    Hexachloroethane - 62%

    Magnesium - 15%

    Naphtalene (or Antracene) - 23%

     

    Red Smoke:

     

    Potassium Chlorate - 25%

    Rhodamine B - 24%

    Para Red R - 15%

     

    Blue Smoke:

     

    Potassium Chlorate - 28%

    Methylene Blue - 17%

    Indigo Pure - 40%

    Wheat Flour - 15%

     

    Green Smoke:

     

    Potassium Chlorate - 28%

    Auramine - 10%

    Methylene Blue - 17%

    Indigo Pure - 30%
