5 Viral Dry Ice Experiments Going Trending on Social Media in 2026

Why dry ice is everywhere

Dry ice is everywhere online right now. What started as a niche interest in science demonstrations has exploded across platforms like TikTok, Instagram, and YouTube throughout 2026. I think a lot of this has to do with increased accessibility. More companies, like Emergency Ice, are offering direct delivery, making it easier for people to get their hands on it.

Another major factor is the desire for visually compelling content. Dry ice creates dramatic effects – fog, bubbles, and temperature changes – that translate really well to short-form video. People are naturally drawn to things that look cool, and dry ice delivers. It’s also a relatively inexpensive way to create a "wow" factor in videos.

Dry ice is solid carbon dioxide. It causes severe burns on contact and can displace oxygen in small rooms. It isn't a toy, and you need to handle it with the same caution you'd use for a hot stove or power tools.

The witches brew effect

The most popular dry ice experiment currently trending is undoubtedly the "Witches Brew" – creating a bubbling, foggy concoction that looks like something straight out of a Halloween movie. The basic premise is simple: drop dry ice into warm water. The dry ice undergoes sublimation, transforming directly from a solid into carbon dioxide gas, and this creates the dramatic fog effect.

Most people add food coloring to create swirling mists. Some add glitter, though it's a pain to clean up. Stick to glass containers like fishbowls; avoid plastic cauldrons because the extreme cold often makes the plastic brittle or causes it to crack and leak.

A frequent mistake is using too small of a container. The expanding CO2 gas needs room, otherwise, you end up with a messy overflow. Also, make sure you’re in a well-ventilated area. While the CO2 isn’t immediately dangerous in an open space, it can displace oxygen. According to the Department of Chemistry and Biochemistry at UC Santa Barbara, understanding the physical properties of dry ice is the key to conducting these experiments safely and effectively.

Sonic bubbles

This experiment is fascinating, and a little mysterious. People have discovered that exposing dry ice to sound – whether through speakers playing music or even just loud noises – can visibly affect the sublimation process, causing the fog to pulse and swirl in time with the sound.

The physics behind this is a bit complex. The sound waves create vibrations in the air, which then transfer energy to the dry ice, potentially increasing the rate of sublimation. I'm not sure about the exact mechanism, and research is still emerging, but it’s a clear visual demonstration of energy transfer.

The biggest challenge with this experiment is consistency. Getting a strong, noticeable effect can be tricky. The frequency and amplitude of the sound seem to play a role, as does the size and shape of the dry ice. It often takes some experimentation to find the right conditions. It's more of an art than a science at times.

Balloon inflation

The dry ice balloon is a classic science experiment for a reason – it’s simple, safe when done correctly, and visually demonstrates the properties of sublimation and gas expansion. You place a small amount of dry ice inside a balloon, and as the dry ice sublimates into carbon dioxide gas, the balloon inflates.

There are limitations, of course. The size of the balloon is limited by the amount of dry ice you can safely use. Too much dry ice can create excessive pressure and cause the balloon to burst. People are experimenting with different balloon materials, like latex versus mylar, to see which holds up best.

Variations include attempting to measure the volume of CO2 produced as the balloon inflates, or using different sized balloons to observe the relationship between dry ice quantity and balloon size. It’s a great way to introduce basic concepts of gas laws and stoichiometry. This experiment, while simple, is still a favorite because it’s effective.

Frozen bubbles

Creating "frozen bubbles" is a more advanced experiment, but the results are truly stunning. The technique involves blowing soap bubbles and then exposing them to extremely cold air created by sublimating dry ice. The cold air causes a layer of frost to form on the bubble's surface, giving it a crystalline, frozen appearance.

This experiment is challenging because temperature control is critical. The air needs to be cold enough to freeze the water in the bubble, but not so cold that it causes the bubble to burst immediately. Bubble fragility is a huge factor too – even a slight breeze can shatter a frozen bubble.

You’ll need some specialized equipment. Insulated containers to hold the dry ice and water, a good bubble solution (glycerin added to dish soap helps), and a way to direct the cold air onto the bubbles are all essential. It’s a bit more involved than some of the other experiments, but the visual payoff is significant.

Metal and temperature shock

This experiment demonstrates the dramatic effect of extreme temperature differences. People press dry ice onto various metal surfaces to observe the resulting thermal shock. The rapid cooling causes visible changes in the metal, such as condensation forming or, in some cases, even slight discoloration.

Different metals react differently. Aluminum and copper tend to show the most dramatic effects, with visible condensation and, sometimes, a slight frosting of the surface. Steel is less reactive, but still shows a noticeable temperature change. It’s important to note that this experiment can potentially damage surfaces, especially if they are coated or painted.

This experiment carries a significant risk of injury. The extreme cold can cause severe burns if the dry ice comes into contact with skin. Never press the dry ice directly against your skin, and be careful not to damage any surfaces you’re experimenting with. I’ve seen people attempting this with expensive equipment, and it’s a really bad idea. Always wear thick gloves and eye protection.

How to handle it safely

It’s essential to follow proper handling procedures to avoid serious injury. Always wear thick, insulated gloves and eye protection when handling dry ice. Never touch dry ice with bare skin, as it can cause severe frostbite almost instantly.

Store dry ice in a well-insulated container, such as a styrofoam cooler, in a well-ventilated area. Never store dry ice in an airtight container, as the sublimating CO2 gas can build up pressure and cause an explosion. Never leave dry ice within reach of children or pets without adult supervision.

If you experience a dry ice burn, immediately flush the affected area with lukewarm water for 15-20 minutes. Do not rub the area. Seek medical attention if the burn is severe. If you’re in an enclosed space and experience difficulty breathing, immediately move to fresh air. For more detailed safety information, consult resources from the CDC () and OSHA.
