uzi strawz (automatic airsoft blowguns with bb control and clips)

Step 4: Inner straw

1. find a straw around 6mm wide that you can blow airsoft bbs through and cut it down the middle lengthwise in about half an inch in and cut one side away. put an airsoft bb onto the open section and blow through the straw to see if it works if it doesn't work cut more away from the section in small slivers.
2. cut a piece of plastic from your little debbie wrapper or your subway straw wrapper about 2/5 of a centimeter wide and about an inch long and tape it to the straw so about 3/4ths of a centimeter is exposed over the section you cut away. this piece of plastic prevents the bbs from rolling out of the front of the straw when you aim down and still lets you shoot them.
3. make the 6mm straw about a inch longer than the inner frame measuring from the v blocker  put the straw next to the inner frame and measure the 6mm straw from the end of the blocker.
4. put two sections of tape around the inner straw and make sure the inner straw slides into the inner frame snugly and barely touches the v blocker.
