Powershot DG25: An epic Lego dart gun

Sneak peek

Recently I was working the sound at the Vacation Bible School (VBS) at my church when I noticed that two of the Mylar balloon sea creatures that were decorating the sanctuary escaped and floated up to the ceiling. Being an expert at Lego weaponry, this was a great opportunity for me to put my skills to good use. To take down the balloons I built a simple Lego gun that launches darts primarily made of mechanical pencils. With its simple but strong structure and large rubber bands stretched to the limit it can launch those darts hard enough to punch right through a Mylar balloon after flying 20 feet straight up. Presenting the Powershot DG25:
