K-Mod Your Supersoaker!




The K-Mod increases the range of your Supersoaker to reach previously unreachable targets. All you need are some rubber bands and a little patience.

Step 1: Dissasembly

What you need will probably vary according to which Supersoaker you have. I got away with using the following:

  • Phillips Screwdriver
  • Long thin metal things for prying
  • Alot of Rubber bands (not pictured)

Just take it apart. Be careful around the nozzle end, and be gentle around the trigger mechanism, if it all comes apart your going to have to figure out how it goes back together.

Step 2: Opening the Pressure Chamber

Locate the pressure chamber, it's the big round thing in the middle of the gun. The chamber should come off really easily, (it's done this way as another safety precaution to stop the thing exploding under pressure - think).

Now unscrew all the tiny screws around the edge of the chamber, and set them aside - it should open easily to reveal the heart of your supersoaker.

Behold! The pressure bulb.

Handle it gently like a tiny fieldmouse, this things powers your gun. It expands to fill the pressure chamber when you pump the gun, filling up with water. The elasticity of the pressure bulb holds the pressure added by the pump until you press the trigger.

Yeah, also this thing probably still has water in it ...

Step 3: Increase the Pooooowwweeerrrr

This is where the elastic bands come in handy.
Wrap the elastic bands around the pressure bulb, like an elastic band ball, and just keep adding elastic bands till your satisfied.

Remember we didn't disable the pressure valve here, so theoretically the top pressure of the gun is still the same, (you can disable the pressure valve if you like ... just don't hold me responsible when you're picking bits of plastic out of your face).

What the elastic bands do is just make it quicker to reach the top pressure of the gun, and therefore reaching maximum pooowwweeerrr sooner. It does also seem to increase the range of the thing, and also the amount of time the gun squirts for in one go.

Results may vary.

Step 4: Reassemble and Test

Put all the screws back in, nice and tight, and put it back together.

Now test your gun, carefully.

You have in your hands great power, ensure responsible use.

    Warning: Using rubber bands will cause the bladder to wear out unevenly, and eventually burst sooner over time. Use 12" party balloons instead. (Trim them with scissors so they fit.) For some blasters, you can layer up to 30 or 40 balloons before the pressure relief valve becomes a problem.

    tl;dr: Use this method http://www.sscentral.org/mods/kmod.html or else the bladder will break much more easily.

    did you know you can also make a water gun into a nerf gun?

    You could mod it so that you have another pressure tank that you fill with compressed air then press a 'boost' button so that it shoots compressed air into the main pressure chamber and gives you a power boost =|)

    on a cylindricle bladder, bike tubes work best.

    There's another way to do this. You just layer ballons around the bladder. -

    I Like IT! you can seriously damage children's eyesight with this. IDEA! add loads of rubber bands (or some other spongy stuff, all round the pressure chamber, so that when the balloon inflates, it has extra pressure pushing it in from the chamber walls

    No offense, but this is a terrible way to K-mod a super soaker. You should layer on balloons, not rubber bands, because the balloons will all expand at the same time, and the pressure is equal throughout. In response to

    lemonie, it can be done, but the pressure bulb has to be cylindrical to get best results with that.

    For more information on how to K-mod a super soaker, visit Super Soaker Central's K mod topic. If you layer on many balloons, you will want to do a "pressure relief valve disable, or check valve freeze. If it is cylindrical, look on the site for colossus modification

    Oh that's a good one. How about a section of tyre inner-tube (which the bulb looks like anyway)? L
