How to Make a Black Light Without Sharpies

To make a black light, you usually need to use Sharpies. But did you know that you can make a black light without sharpies? However, there are other ways to make a black light, which this blog post will explore.


So, in this blog post, we will show you how to make a black light without sharpies. All you need are some basic supplies and a little bit of time. You can either use household items or special materials that you can buy from a store.

By following the steps in this post, you’ll be able to create your own blacklight any time you want! So why not give it a try? Read on for instructions.

Summary: Creating a black light effect without using Sharpie markers can be achieved by utilizing alternative methods, such as repurposing an existing light source or using a smartphone. A black light, also known as a UV or ultraviolet light, emits light in the ultraviolet spectrum, causing certain materials to fluoresce and glow in the dark. This effect is popular for various purposes, including parties, theatrical productions, and other creative applications.

One method to create a black light without Sharpies is to use a flashlight or lamp with an incandescent or LED bulb. Cover the light source with a blue or purple cellophane or theater gel, which will filter the light and produce a similar effect to a black light. Another option is to use your smartphone’s flashlight feature. Download an app that can emit UV light, or create a makeshift filter using purple and blue transparent materials (such as cellophane) to cover the flashlight.

Once you have created your DIY black light, test the effect by shining it on fluorescent or neon-colored objects, which should emit a bright glow in response to the ultraviolet light. Keep in mind that these methods may not be as effective as using a dedicated black light, but they can provide a temporary and affordable solution for casual use.

How Does a Black Light Work? 

Before we show you how to make a black light without sharpies, let’s first explain how a black light works. Black lights emit ultraviolet (UV) radiation, invisible to the human eye.

But when this invisible UV radiation hits certain materials, it causes them to glow in the dark! This is because UV radiation causes the electrons in these materials to become excited and emit visible light.

This is why black lights are often used in crime scene investigations – they can help reveal hidden fingerprints and other evidence that would be invisible to the naked eye.

How to Make a Black Light Without Sharpies: 10 Alternative Ways

1. Use a UV Flashlight

One of the most popular ways to make a black light is by using a UV flashlight. This method is simple and does not require any special materials. All you need is a UV flashlight and a dark room.


To use this method, turn off all the lights in the room and close the curtains or blinds. Then, turn on the UV flashlight and aim it at the wall or ceiling.

The light will reflect off of these surfaces and create a blacklight effect. To make things more interesting, you can use glow-in-the-dark paint or stickers to create patterns or shapes that the black light will illuminate.

2. Using a Paintbrush

If you have a paintbrush, you can use it to make a black light. For this method, you will need to purchase some UV-reactive paint. Once you have the paint, brush it onto a surface and then shine your black light on it.

The paint will absorb the light and emit it, creating a black light effect. You can use this method to create black light effects on walls, ceilings, floors, or surfaces.

You can even use it to paint objects like vases or bowls. Just make sure that the paint is completely dry before you shine the light on it.

3. Use Neon Paint

Another popular way to make a black light is by using neon paint. This method is similar to the one above, but you will need to purchase neon paint instead of UV-reactive paint.

Once you have the paint, simply brush it onto a surface and then shine your black light on it. The paint will glow brightly, providing you with a makeshift black light. One advantage of using neon paint is that it can be easily removed.

If you make a mistake or want to change the design, use a wet rag to wipe away the paint. This makes neon paint a great option for those who are not comfortable with permanency.

4. Use Glow in the Dark Paint

If you want to make a black light that is really easy to use, then this is the method for you! First, all you need is some glow-in-the-dark paint. Then, brush the paint onto a surface in a very thin layer.

When you are finished, expose the paint to light for a few minutes. Then turn off the lights and enjoy your very own blacklight! This method is great for making small black lights that can be used to highlight specific areas. However, it will not produce as much light as other methods on this list.

5. Use Blue and Purple Cellophane

If you want your black light to be more intense, you can use blue and purple cellophane. For this method, you will need to purchase some blue cellophane and tape it over the lens of your black light.


This will help to intensify the effect of the black light. You can also purchase purple cellophane and tape it over the lens of the black light. This will help to make the black light more intense. You can purchase blue and purple cellophane at most craft stores.

6. Use a Black Light Bulb

One of the easiest ways to make a black light is by using a black light bulb. These bulbs are specifically designed to emit UV light, perfect for creating a black light. Simply screw the bulb into a light socket and turn it on to enjoy your very own blacklight.

If you don’t have a black light bulb, you can also use a regular incandescent bulb. However, these bulbs will not emit as much UV light as a black light bulb, so your black light may not be as bright.

7. Use Blacklight Filter on Flashlight

If you have a flashlight, you can use it to make a black light by adding a blacklight filter. This is a very simple method, and all you need is a blacklight filter and tape. First, attach the filter to the front of your flashlight.

Then, cover the seams with black electrical tape. This will ensure that no light can escape from the sides of the filter. Your black light is now ready to use!

8. Use a Fluorescent Light Bulb

Another easy way to make a black light is by using a fluorescent light bulb. These bulbs emit UV light, perfect for making black lights. You need to screw the bulb into a socket and turn it on. You can buy fluorescent light bulbs at most hardware stores or online.

Get a bulb that emits UV light, as not all fluorescent bulbs do. You may also want to look for a black light bulb specifically designed to emit UV light. If you want to make a more permanent black light, you can buy a fluorescent light fixture.

These fixtures come with a socket and a cover, making them easy to set up. You can buy them at most hardware stores or online. Just be sure to get a fixture that uses a black light bulb.

9. Using Your Smartphone Flashlight

Did you know that you can use your smartphone flashlight to make a black light? This method is very simple, and all you need is a white sheet of paper.


First, turn on your smartphone flashlight and hold it close to the paper. The light should be shining directly onto the paper. Next, slowly move the paper away from the flashlight.

You will see that the farther away you move the paper, the dimmer the blacklight becomes. Finally, hold the paper at a distance where you can still see the black light and enjoy your new DIY blacklight!

10. Use Tonic Water

One of the most unusual methods for making a black light is by using tonic water. Tonic water contains quinine, which glows blue when exposed to UV light.

Simply fill a container with tonic water and shine your black light on it to use this method. The quinine in the water will cause it to glow brightly, making it an effective way to create a makeshift black light.

Can You DIY Black Light Without Sharpie?

You can make a black light without Sharpies, but it won’t be as powerful as one that uses them. All you need is a piece of blue or purple transparent plastic, such as a sheet protector. Place the plastic over a regular light bulb and turn it on.


The light will shine through the plastic and create a makeshift black light. While this method will work, it’s not as effective as using Sharpies. The ink in Sharpies contains phosphors, which are chemicals that emit light when exposed to ultraviolet (UV) radiation.

This is what makes them ideal for making black lights. If you don’t have any Sharpies on hand, you can use other permanent markers, highlighters, or fluorescent paints. These all contain phosphors and will work just as well.

Frequently Asked Questions

What Can I Use Instead of a Black Light?

There are many different types of light bulbs on the market that emit different colors of light. For example, a fluorescent light bulb emits a yellow light, a regular incandescent light bulb emits an orange light, and a LED lightbulb emits a variety of colors depending on the type of LED chip it has. You can also use a blacklight to see in the dark. Blacklights work by emitting short-wavelength light (such as ultraviolet or blue) that triggers the release of melanin in the skin. This allows you to see faint outlines and patterns made up of melanin.

Some people prefer to use blacklights because they believe they produce a brighter image. However, this is not always true. Some people find that blacklights make their skin feel uncomfortable because they stimulate the release of melanin. Additionally, blacklights can be harmful if used incorrectly. If you are using a blacklight for entertainment purposes, it is important to take precautions such as wearing protective eyewear and limiting your exposure time.

Can My Phone Turn Into a Black Light?

There is no scientific evidence to support the claim that phones can turn into black lights, and any such claims are likely just scams designed to take advantage of gullible people.
