Watercolor Tips and Techniques

If you’ve been finding yourself stuck on the couch lately, it might be time to get creative! Arts and crafts are a fun and productive way to spend your free time, and watercolor painting is an enjoyable and easy medium to create a masterpiece. We’re here to demonstrate three unique techniques to help you WFH (watercolor from home).

 

If you don’t have watercolor paints around the house, don’t worry—you can easily create your own by combining acrylic paint with water. Just choose your favorite colors and slowly mix in the water until you get the thin, watery consistency of the examples below.

 

 

Salt and Watercolor

The creativity doesn’t have to stop at adding water. Use other household objects like salt for a grainy, textured pattern in your painting. The key to this technique is salting the paint while it’s still wet.

 

  1. Start by painting a small area to ensure it won’t dry up too quickly.
  2. Next, pour some salt on the wet portion of the paint. You can add as much or as little as you’d like!
  3. Finally, once the paint is dried, wipe off the salt to reveal your unique pattern.

 

 

Pro tip: Try out different kinds of salts (such as sea salt) to achieve different sizes, textures, and effects.

Watercolor Drip

This next effect doesn’t require any add ons—just gravity. Make sure you have a paper towel or newspaper underneath your paper for this one since it can get messy.

  1. Choose your watercolor and add a generous amount of water to your paintbrush.
  2. Mix the water and paint together on your canvas, add even more water, and tilt your paper upright to allow the paint to drip. It’s as simple as that!
  3. If the paint is not dripping enough, continue to add water to the painted section with your brush.

 

 

Wet on Wet Blending

 

One of the best things about painting with watercolors is the ability to easily blend colors and create beautiful, unexpected patterns. Combining more than one color while they’re still wet allows them to bleed into one another and create a classic watercolor look.

 

  1. Start with the base color of your choice.
  2. Slowly add other colors and let the water blend them.
  3. Continually add water to help the natural blending process.

 

The best part about this technique is its unpredictability. Just let the water guide your design and see what happens.

 

 

There are plenty of ways to get crafty and creative if you’re stuck indoors. You can even combine all three of these techniques to create a new masterpiece every day! Don’t forget that anyone in the family can be an artist—just add water.

Inside the Witch’s Cauldron: The Science of Dry Ice

It’s the season for all things spooky and scary! From witches and warlocks to jack o'lanterns and sweet treats, there’s so much wonder to behold during the Halloween season.

Looking for a fun activity to get in the festive spirit? With a few simple ingredients, you can make your very own witch’s cauldron for decoration. All you’ll need is some dry ice—and water, of course!

How can ice be dry?

At Aqua, we’re always fascinated (but never surprised) by water’s versatility and the ways that it can teach us new lessons about the world around us. Though there’s nothing spooky about water, it’s a key ingredient in a DIY witch’s cauldron that’s sure to wow trick or treaters.

 The other key ingredient is dry ice, which is exactly what it sounds like: ice without water. That may be hard to imagine, but it’s possible because of carbon dioxide.

Believe it or not, dry ice is colder than ice made with frozen water. Essentially, dry ice is carbon dioxide (with no moisture or air) that’s frozen at -109.3°F, while regular ice freezes at 32°F. So what happens if water and dry ice meet? Let’s just say things can get spooky.

When the dry ice meets water, it immediately undergoes sublimation, which means it changes from a solid to a gas without ever becoming a liquid. The best part of it all? Water is a catalyst that helps to create this phenomenon!

How to make a DIY witch's cauldron

First and foremost, you’ll need the main ingredient: dry ice. If you aren’t sure where to buy it, call your local grocery store to see if they carry it. If not, search online for a supplier near you.

 Next, look for a cauldron at a Halloween store, or use a large cooking pot from your kitchen. Even if it doesn’t look exactly like a witch’s cauldron, your bubbling potions will still look festive.

Fill the cauldron about halfway with hot water and a dash of dish soap, which will help to give you bubbles. Then, using tongs, place small chunks of dry ice into your soapy water mixture and watch as the kettle starts to gurgle and bubble. Remember to handle the dry ice with care—due to its negative temperature, touching it with bare hands can give you frostbite.

To keep the potion going, add more hot water when needed. Your neighbors and friends will surely be wowed by your crafty decor.

Whether you’re trying this craft out in your kitchen with the kids, in the classroom with students, or at a party with friends, we hope you enjoy watching this fascinating scientific reaction unfold.

Happy Halloween!
