This is how big bags look like, but you may go as small as you want. I also just used plastic bags for trash: http://i.ebayimg.com/images/i/262849414982-0-1/s-l1000.jpg

Doesn't have to be straw, you can use any carbon based material (I even used threw away cardboard) (and my own hair, but didn't work), but for bags straw is a bit easier to work with and gives consistent results
