I wanted to make a quick video for some of you asking how to make this working grappling hook gun with the new Bazooka Mini Blaster part. The key is using the bar with 1 x 1 round plate instead of a normal 1 x 1 round plate. Getting the grappling hook to grab on to things is luck but for me it is working about 25% of the time all the time. Let me know how it works for you! #lego #tutorial #batman
