These lasers are crazy bright. Each of the green and red lasers are beamed through motorized diffraction patterns that cast an entire room with hundreds of mini super novas (or fireworks) that explode and reform. It's intense and hypnotically relaxing at the same time. Just set it to flash on/off with a speed that you can control.
The Silver Party Bullet runs off an included 5v power supply. You can tilt the laser show from a flat surface or use its stand as a mounting bracket to the wall or ceiling.
