A few months ago I posted about a floating target system I built for my airsoft pistol. It works well but the balls pop off of the air column and the target balls don't hold up to multiple shots. I finally got around to improving it.

To smooth out the airflow, I used plastic stirring straws. I cut each in half (2.5") and packed 17 into each tube. They hold in with just friction.
For the target balls, I found these Callaway Soft Flight golf balls. They feel like they are made of a dense foam. They float stably and aren't damaged at all when shot. They will be able to withstand hundreds of shots. With those quick improvements the target system is much more reliable and fun. Happy shooting!
