Generally, a value between 1 and 5 is considered a gun). 2.Water bullet: Water bullets are made of water-absorbing polymer materials (such as sodium polyacrylate). Before absorbing water, they are solid small beads, but after absorbing water, they expand into water droplets with a diameter of 6-8 millimeters. 3.Internal mechanism: Composed of plastic, it is programmed to control a 130 DC small motor (speed: 6000-12000RPM, torque: 10 g·cm - 20 g·cm) to rotate and drive the spring to compress, thereby obtaining elastic potential energy to launch water projectiles. 4.The force exerted by a water bomb is approximately 2.5 Newtons. A force of 1 to 5 Newtons is similar to a slight touch or pat and usually does not cause significant pain. FAQ Are you manufacturer ? Yes, we are manufacturer. How long is your delivery time?
