Step 1: The Glue

you then apply water tight glue to the bottom of the bottle top and stick it on to the top of the tank

Step 2: The Drill

you then drill straight through the bottle top and the tank being sure to leave enough space at the sides so the glue can keep the cap attached to the tank.

Step 3: Use It

all you need to do is fill up a bottle that fits the cap with water, and screww it on to the cap. the water will fill up the tank giving you easy refills. you could even carry a few bottles around so that you could refill without going to a tap.

    Pretty nice, you could make more than one REfill on the same gun with this.

    Seems good, but errrr... I recon we can do better, Get a black solar water shower thing ($12.00) And put a tube from that staight into the lid of the waterpistol. Put the back on your back. They all have valves so that you can fill and refill over and over. It will go into the pistol as long as the bags on your top part of your back and the pistol is at your waist. -Cheers, Chris
