Dragon's breath is a wildly popular treat, and for good reason! This deceptively simple snack delivers a dramatic burst of cold followed by a surprising puff of smoke, making it a fun and memorable experience. But how is this magical effect achieved? Let's dive into the science and the steps to create your own dragon's breath.
What is Dragon's Breath?
Dragon's breath is essentially a cereal treat, often made with Fruity Pebbles or similar brightly colored cereal, coated in liquid nitrogen. The extremely low temperature of liquid nitrogen (-320.8°F or -196°C) causes the moisture in your mouth to instantly vaporize upon contact, creating a dramatic puff of "smoke" and a chilling sensation. It's important to understand that the "smoke" isn't actually smoke, but rather condensed water vapor.
What You'll Need to Make Dragon's Breath
Creating dragon's breath requires careful handling of liquid nitrogen, a substance that's extremely cold and can cause serious injury if mishandled. Always prioritize safety. You'll need:
- Liquid Nitrogen: This is the key ingredient. You can usually purchase it from scientific supply companies or specialized gas suppliers. Never attempt to make dragon's breath without proper training and access to liquid nitrogen.
- Cereal: Fruity Pebbles are a classic choice, but other brightly colored cereals will work.
- Large, Insulated Container: A thermos or similar container will help keep the liquid nitrogen cold and minimize evaporation.
- Insulated Gloves: These are crucial for protecting your hands from the extremely cold liquid nitrogen.
- Tongs or Insulated Forceps: Use these to handle the cereal after it's been submerged in the liquid nitrogen.
- Eye Protection: Safety glasses or goggles are essential.
- Well-Ventilated Area: Liquid nitrogen can displace oxygen, so work in a space with good ventilation.
Step-by-Step Instructions for Making Dragon's Breath
Note: This process requires the careful handling of liquid nitrogen. If you are not comfortable working with this substance, do not attempt to make dragon's breath. Consider seeking assistance from someone experienced in handling cryogenic materials.
-
Prepare Your Workspace: Ensure your workspace is clean, well-ventilated, and free from any flammable materials. Put on your insulated gloves and eye protection.
-
Fill the Insulated Container: Carefully pour liquid nitrogen into your insulated container. You'll need enough to fully submerge the cereal.
-
Add the Cereal: Using the tongs or forceps, gently add the cereal to the liquid nitrogen. Make sure each piece is fully submerged.
-
Submerge and Wait: Let the cereal sit in the liquid nitrogen for about 10-15 seconds. This allows the cereal to reach the necessary temperature.
-
Remove the Cereal: Using your tongs or forceps, carefully remove the cereal from the liquid nitrogen. Avoid touching the cereal with your bare hands.
-
Serve Immediately: Place the cold cereal on a plate or tray. Consume immediately to experience the full "dragon's breath" effect.
Safety Precautions When Making Dragon's Breath
- Never touch liquid nitrogen with your bare skin. It can cause severe frostbite.
- Always wear appropriate personal protective equipment (PPE) including insulated gloves and eye protection.
- Work in a well-ventilated area. Liquid nitrogen can displace oxygen.
- Keep liquid nitrogen away from children and pets.
- Do not inhale liquid nitrogen.
- Do not store liquid nitrogen in sealed containers.
- Dispose of liquid nitrogen properly according to local regulations.
What Happens to the Cereal in Liquid Nitrogen?
The liquid nitrogen causes the moisture on the surface of the cereal to rapidly freeze and then sublimate (transform directly from a solid to a gas) when it reaches the relatively warm temperature of your mouth. This rapid transformation creates the visible "smoke" and cold sensation.
Can I Make Dragon's Breath at Home?
While technically possible, making dragon's breath at home is strongly discouraged unless you have extensive experience working with cryogenic materials. The risks associated with liquid nitrogen handling outweigh the benefits for most home cooks.
Where Can I Find Liquid Nitrogen?
Liquid nitrogen is not readily available at grocery stores. You'll need to contact specialized gas suppliers or scientific supply companies to obtain it.
Making dragon's breath is a fun and exciting experience, but safety should always be the top priority. Remember, always prioritize safety and handle liquid nitrogen with extreme care.
