The water cannon using the compressed air according to the present invention can teach students the principle of the cannon, but does not use gunpowder but presses water with compressed air to fire the shell, thus demonstrating to students safely. The advantage is that it can increase the effect.
Description
The present invention relates to a water cannon, and more particularly, to an educational water cannon that fires water shells using compressed air.
Normally, cannons are propelled by the explosive power of gunpowder explosions using gunpowder. However, these gunpowders are so explosive that they are inadequate for students to experiment with. Therefore, there is a need for a safer learning tool while using the principle of cannon.
Therefore, as a learning tool that can explain the principle of cannon while solving the problems of gunpowder, there is a need for a water cannon using water pressure of safety without economic burden.
The water cannon using compressed air according to the present invention for solving the above problems is to pressurize the water with compressed air so that the students can teach the principles of the cannon and can safely demonstrate the compressed air to fire the shell. The purpose is to provide a used water cannon.
Water cannons using compressed air according to the present invention for achieving the above object is arranged on the circumference at intervals of 120 degrees and
The water cannon using the compressed air according to the present invention can teach students the principle of the cannon, but does not use gunpowder but presses water with compressed air to fire the shell, thus demonstrating to students safely. The advantage is that it can increase the effect.
