The All Purpose Launcher uses spring power to launch any item small enough to fit into the barrel. A long device such as a stick or the supplied pusher in the picture is used to push down the spring and lock it in place. The switch on the handle release the lock and uses the power of the spring to launch the item. There is only one setting for compressing the spring as this toy is designed to be as simple and as cheap as possible.
The materials of this device are metal for the spring and plastic for all other parts. Plastic is the main material to make the device as cheap as possible while the spring must be metal in order to produce a strong launching effect. This device is aimed to have a construction cost of around $10.00 mostly for the spring and the high tolerance required to make the lever consistently work. This product is for ages 10 and up because the spring loading will hold a lot of force that may be harmful to younger children.
The fundamental principle involved with the launcher is springs. The spring is the main aspect of this device and users will learn how force relates to loading the spring and how the spring releases potential energy to launch items. The shining quality of this toy is that it is very cheap and can be used to launch whatever the user desires at any moment in time (as long as it fits into the barrel of the launcher of course).
