Description

technical field [0001] The invention relates to the field of teaching instruments, in particular to an air cannon for teaching. Background technique [0002] The air cannon is a device that uses the jet of compressed gas to knock down obstacles. When conducting scientific inquiry experiments, the teacher will often instruct students to make an air cannon, and use the finished air cannon to knock down disposable cups and other objects , since the air cannon produced has no aiming device, there will be some deviations when demonstrating knocking down disposable cups and other objects. In addition, the air cannon has no lights, which also reduces the playability. Contents of the invention [0003] The technical problem to be solved by the present invention is: the purpose of the present invention is to provide a kind of air cannon for teaching, to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the prese...
