be made from Popsicle sticks. The individual sticks are held together by either rubber bands, tape or glue. They can also be cut or carved to the required shape. It is generally limited to pistols and sniper rifles, as only one or two shots can be loaded on most guns, but semi-automatic ice-cream stick guns have been made by determined amateurs. They can also be adapted to fire arrows or other small objects with the rubber bands. In some guns, the handle doubles as a trigger, but having a separate trigger and handle provides much better accuracy. Rubber band guns can be made using only Popsicle sticks, staples, and rubber bands of various styles and sizes. This specialized technique developed and honed by then-high school student Stuart A. Burton is very malleable and can be utilized to develop very advanced and complicated rubber band guns. For instance, using levers and sliding mechanisms, one can make a pump-action shotgun. Using simple geometry and specialized positioning, you can easily make semi-automatic and 2-shot burst-fire weapons, as well as more complicated fully automatic weapons using paperclips as an axis for a rotating firing piece. Occasionally, other materials (like bamboo skewers, for instance) may be used in the making of the gun. Sights, foregrips and magazines to hold extra rubber bands may also be made according to the owner's preferences. Through creativity and imagination, one can make detachable sights, grips, stocks, silencers, and under-barrel shotguns or grenade launchers. K'Nex Rubber band guns can be built from K'Nex. Such constructions can include handheld pistols, automatics and sniper rifles. Some K'Nex guns work using the escapement mechanism seen in semi-automatic rubber band guns, while some more advanced types have hinge triggers that are more reliable, allow for more bands on a barrel, and have a more realistic trigger pull. Lego Most rubber band creators start out with lego, as it allows users to easily express ideas. In early 2007, Sebastian Dick built a motorized rubber band rotary gun entirely from Lego, capable of firing 11 rounds per second. Many other builders on YouTube followed suit, building string-operated miniguns, while some shoot actual bricks. Many RBGs are built out of Lego, from simple hinge guns to complex fire-rate-dampening automatic rifles. Lego rubber band gun mechanisms can also be used to launch light projectiles of various types, from small bricks and paper planes to wooden skewers. Lego rubber
