Haunted houses are always a fan-favorite Halloween pastime, and if you’ve ever been inside one, you know that they are full of intricate decorations and special effects.
We can’t help but appreciate all the art and craftsmanship that goes into creating these spooky attractions, especially when we know that many of the special effects that make haunted houses so terrifying are created with—you guessed it—water.
Read on to see our five favorite water-filled haunted house effects (and to learn how they work).
While you may be thinking this spooky classic is nothing more than face paint or ketchup, it’s actually a water solution. One of the best ways to make fake blood is to use water, cornstarch, corn syrup, onion flakes and red food coloring.
The fog you see at haunted houses or in scary movies is actually made with dry ice. Dry ice is the solid form of carbon dioxide, so when it changes states, it actually turns directly into a gas. All that’s needed is a large bucket or cauldron about a fourth of the way filled with hot, hot water. Once dry ice is deposited into the water, voila: you’ll start to see a thick, spooky fog. (Remember: Never handle dry ice with bare hands as it can damage your skin due to its extremely low temperatures.)
Witches brew is essential for any haunted house. While the solution can be made with a number of odd ingredients, water brings it all together. Getting the perfect icky green witches brew is as simple as boiling up a pot of water, adding a drop or two of dish soap and pouring in some food coloring. Of course, you can always add some candy eyeballs or gummy worms to make the bubbly brew extra spooky.
Specimen jars are among the creepiest of haunted house decorations: they combine both odd little creatures and greenish liquids you’d imagine smell awful. In reality, though, specimen jars are just filled with water, a couple of drops of food coloring and small toy animals or doll parts.
Plus, specimen jars can become even creepier by turning them into a sensory experience. Adding foods like cold spaghetti and peeled grapes to a jar and asking haunted house visitors to close their eyes and stick their hands inside is sure to produce some shrieks.
Slime is a perfect haunted house decoration: It’s easy to make, fun to play with and slippery as can be. Though it may feel like it comes from the bottom of a snail or a big fish, slime is actually made with a simple mixture containing water. The mixture creates a medium between solid and liquid that makes for some great ghost sludge or monster ooze. The best part is that the slime can easily be cleaned up with warm water, too.
