<P> According to a line spoken by Egon in Ghostbusters II, each pack's energy cell has a half - life of 5,000 years . Knobs on the main stock of the proton pack can perform various functions to customize the proton stream, including adjustments for stream intensity, length, and degrees of polarization . In the cartoon series The Real Ghostbusters, the maximum power setting for the proton packs is "500,000 MHz," which possibly refers to the rate of positron collisions occurring within the pack's accelerator system . In the cartoon the packs also have a self - destruct mechanism capable of affecting at least a half - mile radius . The Real Ghostbusters and the Extreme Ghostbusters also made proton packs less efficient with power cells, allowing them to run out of energy when appropriate for dramatic tension; in the latter show, the proton packs require replaceable power cartridges . </P> <P> The IDW monthly Ghostbusters comic storyline has shown the movie pack, a boson dart capable pack and the Extreme Ghostbusters pack in use . The IDW comic also shows a proton pistol attachment to the movie pack being used by Winston while hunting down Slimer . </P> <P> There's something very important I forgot to tell you! Don't cross the streams...It would be bad...Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light . </P> <P> Crossing the streams was initially discouraged, as Egon believed that "total protonic reversal" would occur: this effect would have catastrophic results (see quote above). However, in a desperate effort to stop the powerful Gozer the Gozerian, Egon noted that the door to Gozer's temple "swings both ways" and that by crossing the streams, they may be able to create enough force to close the door on Gozer and its control . As the Ghostbusters cross the streams, the combination of that much energy closes the door to Gozer's dimension and severs its ties to our world . The resulting blast destroys a good portion of the roof and blows up the Stay Puft Marshmallow Man . </P>

Ghostbusters what happens when you cross the streams
