We did this, it was fun. Someone measured the width of the floor and then got pvc pipe, different lengths to make it as much like a foosball table as possible. Of course it also depends on how many youth will be holding onto the pipe! We had leaders and some adults who were bored come join us. We stuck masking tape on the floor (painting tape is good, won’t stick forever) to mark the lines that you had to remain on. You could go along those lines side to side but feet had to remain on the lines and your 2 hands had to stay on the same spots on the pipe at all times as well. This helps keep the spacing right, and people won’t be kicking each other as much. We used a bouncy kick ball as well, or a kid’s plastic ball so it wouldn’t hurt if it hit you.
