How to Make a Glowing Glass Jar

Make the glowing jar at night. You will need to use glow sticks for this project. Since glow sticks only shine for a limited time, it's best to do this at night, ensuring you don't waste their brief glowing period.

Choose the right jar. You can use a large or small jar, but smaller jars tend to shine brighter. The glow-in-the-dark material will be more sparsely distributed in larger jars, meaning you'll need more glow sticks. Alternatively, you could use a jar shaped like a lightbulb with a cork lid.

• You can use a colored Mason jar, or even dye your own jar by mixing clear wood glue with a few drops of food coloring, then painting the jar with this mixture.

Get some glow sticks. Any type of glow stick will work, but glow sticks around 15 cm in length will be brighter than the ones used for bracelets and necklaces, which have a shorter glow duration. The number of glow sticks you'll need depends on the size of your jar. Larger jars will require more glow sticks.

• You'll need two or three glow sticks, depending on the size of your jar. For example, a 0.5-liter jar will need two to three 15 cm glow sticks.
• Buy glow sticks that have a long glow time. Most glow sticks only last for 2 to 3 hours, but there are some that last up to 4 or 6 hours, and some even glow for up to 12 hours. The packaging will tell you how long the glow lasts. The longer the glow, the more time you have to enjoy your glowing jar.
• Purchase glow sticks in a variety of colors. Most glow sticks come in basic colors like red, pink, orange, yellow, green, blue, purple, and white. You can create unique colors by mixing different ones together. For example, mixing blue and green will give you a teal color.

Activate the glow stick. Hold the glow stick with both hands and bend it until you hear a crack. This action will break the glass tube inside and release the chemicals that make the glow stick light up.

Cut one end of the glow stick over the jar. You can use a craft knife or scissors. Glow sticks are non-toxic, but their chemicals can irritate your skin. Be sure to wear rubber gloves while doing this.

• If children are performing this step, adult supervision is necessary.
• Place a small mesh strainer over the jar opening. It will catch any tiny glass fragments from the glow stick. Do not use this strainer for food preparation after this step.

Pour the liquid into the jar. Hold the glow stick upside down and pour its contents into the jar. You might need to shake the glow stick a little to make sure all the liquid pours out.

• If any glass fragments fall into the jar, you can remove them with a plastic fork or spoon. Dispose of the fork or spoon afterward and do not use it for food.

Sprinkle some glitter. You can use any kind of glitter you like, but shimmering glitter will make your jar look even more beautiful due to its light-reflecting properties. The amount of glitter you'll need depends on the size of your jar and your personal preference. For example, to make a 0.5-liter jar look attractive, you'll need around 32 grams of fine glitter.

• You can choose glitter in shapes like flowers, hearts, and stars.
• For a more striking effect, mix fine glitter with larger glitter in different colors.

Add something inside the jar. The liquid from the glow stick will cause the glitter to stick to the sides of the jar, but you can make the glitter appear to float by adding a piece of white tulle or mesh fabric. You can also use cellophane. Simply cut a piece of paper or fabric you like, gently crumple it, and place it inside the jar. It should be large enough to fit comfortably in the jar without filling the entire space.

Seal the jar tightly and shake it. Shake the jar so that the glow-in-the-dark liquid and glitter cover the inside of the jar.

Decorate the jar. You can make your jar even more beautiful by decorating the lid with glitter or covering it with a nice piece of fabric. Check out the lid decoration guide in this article for more creative ideas.

Bring the jar into a dark room. The glow stick liquid will still glow in daylight, but it will shine much brighter in the dark.

Purchase a battery-powered LED string light. The best type of LED string lights for this project are small ones that come with a compact battery pack. These are often used to decorate miniature house models. You can also use standard-sized LED string lights, but make sure they are battery-operated and of a moderate length. Opt for white or silver wire for a clean look. LED lights are preferred because they generate less heat than regular bulbs.

• If you want your jar to have a plant-like effect, choose green wire lights.

Find a suitable jar. You can use any jar you like, but make sure it’s large enough to hold both the LED light string and the battery pack.

• Use a colored glass jar. You can dye it yourself by mixing clear wood glue with a few drops of food coloring and painting the jar with this mixture.
• To create a more magical glow, you can use white glue to coat the jar. White glue will slightly blur the light, so you can still see the glow without the wires inside being visible.

Attach the battery pack inside the jar. Use tape to secure the battery pack to the bottom of the jar. The battery pack will stay hidden once you've finished decorating. Just make sure you can still access the switch to change the batteries easily.

• If the battery pack doesn’t fit into your jar, consider using a Mason jar with a two-part lid. Remove the circular insert and keep the rim. Attach the battery pack to the top of the lid and cover it with fabric. You can use ribbon or twine to secure the fabric around the lid once it’s in place. The LED string can then be fed into the jar through the hole in the lid.

Place the lights inside the jar. Arrange the LED string so that it fills the jar completely.

Add something else to the jar. When you add a piece of tulle, mesh fabric, or cellophane paper, you’ll diffuse the light and create a more magical glow. This also helps hide the wires inside the jar. Cut a piece of paper or fabric that is slightly larger than the jar and place it inside. It should be large enough to fit nicely without taking up all the space.

• Instead of tulle or cellophane, you could place some dried moss inside. This will make your jar look like a tiny forest.

Turn on the lights and seal the jar. Flip the switch on the battery pack and screw the lid back on tightly.

Decorate the jar. If part of the battery pack is still visible, you can cover it by tying a ribbon around the neck of the jar. For more decoration ideas, check out the glowing jar decoration guide in this article.

Enjoy your creation in a dark room. The lights will glow during the day, but they will look even more beautiful when you bring the jar into a dark room (especially if you’ve added a frosted effect to your jar).

Choose a clear jar. You can use any size jar, but make sure the opening is wide enough to fit a paintbrush inside. Whether it's a glass or plastic jar, it doesn’t need a lid. Just be sure to pick a clear one, as you’ll need to paint inside.

Clean the jar thoroughly. Use alcohol to wipe both the inside and outside of the jar. Any oil or residue left inside will prevent the glow-in-the-dark paint from sticking properly.

Purchase glow-in-the-dark paint. You can use fabric paint or acrylic paint, but it must be specifically labeled as ‘glow-in-the-dark.’ Unlike glow sticks, this type of paint is reusable. This means your glowing jar can shine multiple times by simply placing it under sunlight to ‘recharge.’

Select your painting tools. Since you'll be painting round dots inside the jar, you can use a paintbrush or a wooden stick. Try using brushes and sticks of different sizes to create dots of various sizes.

Prepare the paint. Shake the paint well to evenly distribute the glow-in-the-dark particles. Pour about a tablespoon of paint onto a plate. Acrylic and fabric paints dry quickly, so don’t pour out too much at once, or it might dry before you finish. You can always add more paint if you run out.

Paint small dots inside the jar. Dip your paintbrush or a wooden stick into the paint and make small spots inside the jar. If you use multiple colors, apply one color at a time.

Wait for the paint to dry before sealing the jar. This process may take anywhere from a few minutes to a few hours. Check the instructions on the paint container to find out when it will dry. You can place the jar in the sun to let the paint dry and 'charge' its glow effect at the same time.

Make the paint glow. Set the jar in a well-lit room or place it under sunlight for about 10 to 15 minutes.

Decorate the jar. You can paint the jar lid with a different color, add glitter, or wrap fabric around it. You can also place mesh fabric, tulle, or cellophane paper inside the jar. For more decoration ideas, check out the guide in this article.

Enjoy your creation. Once the paint has absorbed enough light, place the jar in a dark room. The paint will glow, giving the effect of tiny fairies inside. When the glow fades, you can place the jar back under light for a few minutes to recharge it before returning it to the dark room.

Add some items into the jar. Materials such as mesh fabric, tulle, cellophane paper, small plush toys, or moss can diffuse light and make the jar look more magical. Choose a soft, light-colored or white tulle or mesh fabric. For cellophane paper, pick a shimmering type to reflect light better. You can also place a small plush bear or some moss into the jar.

Place a fairy inside the jar. Buy a small figurine of a fairy and glue it to the inside of the jar lid. Close the lid and flip the jar over. The lid will now serve as the base, creating something similar to a snow globe.

• Attach some moss, small stones, and tiny flowers around the fairy to conceal the back of the lid while creating a charming little dwelling for the fairy.
• If you can't find a fairy figurine, you can create one by buying a human figure and gluing butterfly wings to its back.

Paint the jar lid. To make the jar look more vibrant, you can paint the lid. Start by sanding the lid, then use a soft cloth to remove all dust. Paint the lid using acrylic paint with a brush or sponge. You can also use spray paint.

• If you're using spray paint, shake the can until you hear the rattling sound inside. Hold the can about 15 to 20 cm away from the lid, and spray a thin, even coat. Let it dry before applying another coat. Always spray in a well-ventilated area to avoid inhaling fumes.

Cover the lid with glitter. For a sparkling lid, apply glue to the lid and then sprinkle glitter over it. Don’t rush to spray paint the jar just yet. Gently lift the lid and shake off any excess glitter. Wait for the glue and glitter to dry before applying glue and glitter to the jar itself.

• Place a sheet of paper under the lid while working. When finished, simply fold the paper in half and pour the leftover glitter back into the container.
• To secure the glitter, wait for the glue and glitter to dry, then spray a thin layer of clear topcoat. Allow it to dry before applying a second coat.

Cover the jar lid with fabric. Place the lid on a piece of fabric and draw a circle that is 3 to 5 cm larger than the lid itself. Cut out the circle and place the lid onto the jar. Place the fabric circle over the lid, smoothing down the edges around the jar. Wrap a ribbon or twine around the neck of the jar to secure the fabric in place, and tie it into a bow.

Add accessories to the lid. Take a few colorful glass beads and glue them to the lid. You can also use buttons, decorative stones, or small figurines to embellish it.

Tie a bow around the jar neck. You can also add a flower or a gemstone in the center of the bow for extra decoration.

Use colored glass jars. Mason jars come in various colors like blue, green, and purple, which will make your glowing jar look much more appealing. If you can't find a colored glass jar, you can easily dye one by mixing wood glue with a few drops of food coloring. Paint the mixture onto the jar with a brush or sponge.

• You can also use white glue to either brush or spray it onto the jar. This will give the jar a frosted appearance, which works perfectly for placing string lights inside it.

Attach a fairy silhouette with black paper. You can print fairy silhouettes on paper and cut them out. Use tape or glue to attach them to the side of the jar.

• These jars are best appreciated at night when their glow stands out the most.
• Enhance the appearance of your jar by adding some creative decorations.
• Opt for mystical colors like white, pink, and purple to give it an enchanting feel.
• Materials like tulle fabric or shiny paper inside the jar can help diffuse the light beautifully.

• Be cautious when cutting open glow sticks, as they contain tiny glass shards.
• Avoid swallowing or touching the liquid inside a glow stick. The packaging may label them as 'non-toxic,' but the chemicals can still be harmful and may cause skin irritation.
