Step 2: Making a Water Tube
This step is optional and you can skip it if you already got a small water tube.
It’s possible to use the outer isolation on a power wire as a water tube. To do this we need to remove the inner copper wires without damaging the outer rubber.
Start by cutting a length of wire. I used the wire from an old power cord I was going to throw away. You only need about 25 cm or 10 inches.
Strip away part of the isolation on one of the wire ends. Use your pliers and start pulling the inner wires. You don’t need much just enough to get a grip later on.
We’re going to soak the wires in hot water to soften the plastic and make it more manageable to us. Fill up your sink with really hot water and keep the wire under for at least 5 minutes.
Now it’s time to finish what we started. Use the pliers to get a solid grip on the inner wires and start pulling. Don’t strain too much or the wires might snap. Hold the wires while pulling downwards on the isolation. This is hard at first, but suddenly the isolation is gonna release it’s grip and the wires will slide out.
Perfect, you now made yourself a watering tube!
