How to fix a square shooting balloon? Is there a video?
It's simple. You first find a board, then nail two rows of nails regularly, and then wrap a rope around the nails. Two points need to be emphasized, 1. The distance between each row of nails is exactly the length of the diameter of a balloon. 2. Be sure to find a big nail and wrap it around the top of the nail, so that you can catch the balloon at a distance, so that the balloon will not fall!
