Are you holding a party near a swimming pool, a lake, or maybe even the beach? Then you must experience the sheer beauty of the water cake fireworks. The fireworks we usually see shoot straight up to the sky. But these ones are specifically designed to shoot at an angle over a body of water. How do water fireworks work? The food coloring is denser than water, so it sinks to the bottom of the jar. As it sinks, it begins to mix and slowly dissolve into the water. As the dyes spread out, they leave a trail resembling fireworks. And what good will shooting at an otherwise odd angle do? Well, when you put these fireworks on the edge of a pond or lake, and they shoot at that kind of angle, it will look like the fireworks came straight out of the body of water itself. A magical scene will uphold in front of you, and it's only a matter of time before you get obsessed with water cakes. To get the best results, they should be displayed on a dock or a raft floating on the lake. However, keep in mind that they are NOT waterproof!
