Glowing water is one of the easiest Halloween special effects there is to create. All it takes is some water, food coloring, or water based paint, and some glow sticks. The type of glow sticks that you use is the same type you can buy at novelty stores, or as necklaces and bracelets. This effect can be used in a water fountain, a bowl of punch, or any small area of standing water.
Simply fill with water, and add the color of food coloring, or paint that you need, and add a glow stick. If possible, use the appropriate colored glow stick to go with the color of water. When you are finished, you should have a liquid that appears as if it is giving off an unearthly glow.
This can work great for a ghostly fountain, a magical potion, especially if you ad a bit of dry ice to it. You can also use this Halloween special effect for you witch’s caldron.
