After remembering something from WWN I finally picked some up, Glycerin (Glycerine in the UK). This stuff is expensive, more than $3 for a bottle. For those of you thinking "What the Hasbro HQ does this do," it is supposed to increase your range 5 to 10 feet at his amount, claimed by Big Bee. You are supposed to mix it 19 parts water and 1 part glycerin (5% Glycerin). One bottle, which actually is for skin care and making beer, should be good for about 2.36 liters of water. I am unsure about how this will affect a CPS sytem, I will test it on some of my CPS tubing and see if it reacts.
This stuff will make your water toxic! Do not drink it, and contact poison control ASAP if anything happens.
This really is mostly a test that I am recording online. I am still yet to test it, but if it works them I might use it. Currently I think it is too expensive and should only be used for snipers who need all the range they can get. With a good APH I think you could get easily more than 60 feet range, likely close to 70. With a gun designed purely for sniping I think that more than 70 feet could be easily achieved.
I also will be finding other "additives" and testing them. I also will test if using more than 5% will increase range. Wetting agents is what I think they are called, I hope I can find something cheaper and that comes in larger amounts.
