How to: Load + Launch

Posted by Apptivus (Creator)

Some of you have been asking to see a little more detail with the loading and launching of the Pennypult. So here it is! We went through many different prototypes, and the first 3 or 4 were more of a traditional trebuchet - which included a sling. We tested prototypes of different sizes and styles for accuracy, efficiency and distance. In the end, the design you see now came out on top. Slings often resulted in misfires and often ended up in a tangled mess. The sling-less design proved to be much more reliable and easier to load. All of this came with no sacrifices in performance.

To load - You start by hanging the projectile string onto the arm hook. You then lift the weight basket over to secure the projectile in place. To prepare for launch, place the launch ring onto the rod as shown in the video above.

The Pennypult kit will come with 5 projectiles. They won't necessarily be with orange string, but we used something bright in this video to help you refer to the projectile object. Because the Pennypult is a sling-less design, this ultimately allows you to create many custom projectiles! Pretty much anything you can tie to a string. Beads, hex nuts, rocks, pet treats... You name it, we've probably tried it! The kit will come with extra string, one that we thinks works best, for you to create your own custom projectiles.

To launch - Simply tug on the string. That's all there is to it! We've found projectiles to launch 35ft on an average, and sometimes more. Play around with different objects as projectiles, and you'll be sure to find your favorite.
