I wanted to see how they penetrated each other. Well after the first shot, the box split open and all my papers fell out.

I stack all the newspapers about 3 feet high and tied lengthwise and crosswise with lumber string from Home Depot and let it sit in bathtub or 55 gallon drum. Make several bundles and let soak overnight and the next day, it has expanded but secured well from the string and put two 3 foot stacks together inline and shoot. Stays together until you cut the strings to inspect. Hope it helps.
