Pump Action Pencil Launcher

A pencil can be very dangerous - when The Slingshot Channel builds a weapon around it!

The "Nerd Revenge 2000" is a homemade pump action slingshot crossbow that can fire 10 razor sharp pencil in under five seconds. The "arrows" travel at an impressive 100 miles per hour, fast enough to go through a apple!

The compact weapon (24" = 60cm) can also fire a "devilled" version if a pencil, with an achery field tip glued in. Then the once so harmless pencil is turned into a deadly projectile!

The design was inspired by the Chinese Repeating Crossbow, but the awkward repeating action has been replaced by the far better "pump gun" method. The rubber bands are pre-tensed to 300% and stretched to 500% when you shoot. This means you get good power at a relatively compact size. My experiments with super slomos and the thermal test series laid the ground for this new concept.

This is probably the most fun slingshot I ever shot!

  3. I hope you will put some close-up photos of this weapon in your galley. You could also change the pencil magazine to a vertical ball bearing magazine. Then you would have a mini-pump rifle.

  9. I'm curious about how the pencils would do on balistic gelatin at a distance of 2-5 meters. They're pretty impressive going into that cardboard box.

  11. Those who are a gay or bi-sexual man who is looking for the way to obtain a sizegenetics that should cause you to be feel a good deal better, then going online to one service that will actually list sizegeneticss, their photos and their vicinity of their practice pores and skin look way to go about finding whatever you are looking for. You it's best not to should receive a chance on ads that usually don't feature the photos of the sizegeneticss as ideally you should be positive that there will be no misunderstandings that you know that which you are looking for in the case of getting a gay sizegenetics.
