Liquid Weapons

That seems to make it a bit op. Leave the bomb action to the the nitro-glycerin.

 

I like the implications of use behind this. weapons with high knockback would be very useful, especially in swarm situations! And admit it. It would be awesome to shove people around with a water hose style weapon when you're bored. *shot*

 

What if you had a form of squirt-gun duct-taped to a tazer.... The water would do Electric damage, the tazer could be a form of augumentation or accesory to the weapon. You could fill that squirt-gun with say.. the napalm, you could then attach a lighter or torch or something to make a make-shift flamethrower but can be taken apart to be used as a squirt gun and lighter seperatly. also if there are glowsticks like in terraria you could fill the gun with the glowstick's liquid to spray on enemies/players/blocks to make them glow in the dark for a short amount of time, like 30 seconds to a minute.

 

Volcanic bombs won't explode, they will just create a block of lava and possibly launch fireballs.
Also, there are some more suggestions for liquid weapons(liquid is measured with liquid units(LU), 1 LU = 1 bucket worth of liquid):
Liquid weapons shoot drops instead of actual blocks(Volcanic bombs are the "drops" for lava)
Water Cannon can be charged(hold LMB to charge and release it to shoot).At full charge, the drop is worth 4 LU.Hold RMB to fire the cannon like a machine gun.
Geyser Mines can be used multiple times, you just need to load them with liquid(max load 10 LU) or hook up a fluid pipe to it.
Lava can be only used with a special modifier
Modifier suggestion:
Capacity:Applied to Water Cannon and Geyser Mines.Increases max charge for water cannons by 2 LU and full load of geyser mines by 10 LU.(You can have Capacity II and Capacity III modifiers, but these are harder to craft.It's kinda like Minecraft enchantments)
Shotgun:Water cannon gains a shotgun effect:instead of shooting one big drop, it shoots a barrage of small ones.Also, increases full charge to 12 LU.Capacity modifier will add 4 LU instead of 2.
Charged(I,II and III): Deals additional electric damage.Will not work with Oil, Magma or Cement.
Lava proof: Allows the use of Magma in liquid weapons.
Pressure(I,II,III and IV):Increases range and knockback.

 

i love the sound of this idea it would open up to some fun situations

 

bump
Aka another modifier "Flooder" makes drops spawn liquid blocks...
