Hi Everybody ( Hello Dr. Nic) I've been trying to make my own vortex rings now for quite a while and I thought you all would like to know the system I settled on. I found some stuff at a local craft shop called Card Stock paper. Its just reeally thick construction paper from what I can tell. Once you get the card stock cut out some 5.5 x 1.25 inch rectangles. Sorry for the non metric measurments. Once you get the rectangles (you can usually get about ten per page) cut out, measure .5 inches in and make an even line going down the rectangle. The rectangle of paper is now devided up into two sections, one bigger than the other. Fold the bigger part in half and then fold it again to where you have an edge thats 3 times as thick as the other. Then take some electrical tape ( the good kind most cheaper brands wont stick to paper) and covere the buldge down the length of the paper. Put one more strip of tape on the back of the paper. Rub the now tape covered piece of paper on a sharp edge to give i a nice curl. After this connect the ends using a piece of electrical tape. Once thats done your left with a Vortex ring that goes just as far and is just as accurate as a normal ring and a whole lot cheaper. The only downside is if they get wet they fly apart considering they are made out of thick papere and electrical tape. But most people with Vortex guns use them primarily indoors so moisture shouldnt be to big of a problem. I hope this helps and happy nerfing. If I left anything out or you have any quesions just ask.
