One question often asked is "How do I keep the wet stuff from making my display go BANG!"
Waterproofing is something that should be seriously considered. For a number of reasons.
Firstly - Safety! Yours, your visitors and your house.
Secondly - Convenience. There is nothing more annoying than resetting circuit breakers when water shorts out your power.
There are several ways to water proof. I find this to be the most effective way to keep those little suckers dry. Even though it's summer you'd think there would be little need to waterproof but many of us run an irrigation system over the summer, and it still rains. I remember in 2006 we had a rain storm so heavy it flattened the flowers in the garden.
Simply it goes like this.
What you will need:
Cut the thin end off a drink bottle and place over the top. Making sure it covers as much as possible.
If it's going to be seen, you could paint it or decorate it.The photo is pretty much self explanatory.
Does water get up underneath the bottle?
Generally speaking No. But, place the sticks with the bottles on them where you want them and turn on your irrigation system to test. If water does find it's way up - just move it.
Why do you leave it open and not sealed in a bag?
Sealed plugs sweat. Specially if left in the heat or sun. This moisture can't escape and can cause corrosion or a short. HOWEVER in some cases this does work
