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 an 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The design was inspired by the Chinese Repeating Crossbow, but the awkward repeating action has been replaced by the far better "pump gun" method.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!
