Could a Star Wars type Blaster Gun ever be made? Or is it physically impossible? If yes, how would this be done?

If you shot it, would you be able to see the projectile/beam? Would it just be a big laser? Or would it have some substance to the shot?

I am completely serious about this.

Of course a blaster is possible, but it is important that you understand that a blaster is not a "laser".  A blaster generates and propels a quantity of superheated and ionized gas contained enclosed within a temporary particle shield.  The shield contains the plasma so that it doesn't immediately burst into a flash of heat upon contact with air, burning the user and anyone nearby.

As for how to build one, simply tune a particle shield generator so that it creates a weak and entirely enclosed field.  Then, introduce a pellet of highly pressurized tibanna gas.  The pellet, as it passes through the particle shield will become super heated, burning away the casing and releasing the ionized gas into the shielded space.  Finally, engage an electromagnetic coil while overloading the shield generator.  The overloaded shield generator will allow the field to exist independently for a short time while the EM coil accelerates the projectile toward your target, leaving a glowing trail of hot atmosphere in its wake.

When striking a solid target, the particle shield will heat and displace the target substance before collapsing entirely, generating a sort of armor-piercing effect.  When the particle field collapses, the superheated gas explodes, further displacing armor and releasing an electrical pulse that tends to overload nearby electrical systems.

*IRL, can you make one now?  Not really.  No force fields like the ones they have in SW.*
