Got to be one of the simplest ways to create a really cool Halloween decoration. Add water to a jar half way. Submerge an old Halloween mask and arrange to make it look as real as possible. Here we used an old lady mask but don’t be afraid to use those demon and monster faces as well. Then fill with water carefully all the way to the ridge. Let sit undisturbed for about an hour to release and air. You can add a tea bag to get a dirty water effect – just don’t make it too dark. Several of these placed on a shelf or table with candles would be really neat.
