What Is a Lightning Storm in a Jar?
The Lightning Storm in a Jar is a visual science craft that uses warm water, oil, food coloring, and a fizzy tablet (like Alka-Seltzer) to simulate the look of lightning flashing through storm clouds. It’s the coolest kind of controlled chaos — safe, easy to make, and absolutely stunning to watch.
The best part? You can tweak the colors, light it up in the dark, and add glow-in-the-dark elements for a jaw-dropping sensory experience.

How to Make a Lightning Storm in a Jar (Step-by-Step)
Step 1: Create the Stormy Sky
Fill your jar about ¾ full with warm water.
Add several drops of blue, purple, and dark gray food coloring. Stir gently to mix. For lightning flashes, add 1–2 drops of yellow or white food coloring.
Step 2: Pour in the Oil
Slowly pour vegetable or baby oil into the jar until nearly full.
Watch as the oil floats on top — a perfect example of liquid density in action!
Step 3: Start the Storm
Break an effervescent tablet in half and drop it into the jar.
As it fizzes, it sends bursts of colored water shooting up through the oil like lightning cracks — it’s so cool to watch.
Step 4 (Optional): Make It Glow
Turn out the lights and shine a flashlight underneath the jar to enhance the lightning effect.
Want more drama? Add a dab of glow-in-the-dark paint inside the jar or on the outside for that eerie glow. 👻⚡
What to Pair With This Craft
Make it a full sensory experience by pairing your jar with:
- 🎶 Thunderstorm soundtracks in the background (YouTube and Spotify have tons!)
- 📚 Books about weather or storms, like “Flash, Crash, Rumble, and Roll” by Franklyn M. Branley
- 🍪 A cozy snack like warm cookies and milk for post-storm storytelling
Tips for Best Results
- 🌡 Use warm water — it speeds up the fizz reaction and helps color spread better
- ⚖️ Don’t overfill — leave space for the bubbling action!
- 🔄 Reboot the storm — just add another fizz tablet after it settles
- 🧼 Place your jar on a tray or plate to catch any overflows
Storage & Cleanup
This craft is best enjoyed in the moment, but if you’d like to reuse the jar:
- Store it with the lid off until fizzing stops
- You can reuse the oil/water mixture — just add new fizz tabs when ready
- Pour contents down the drain with hot water and soap when you’re done
- Wash the jar thoroughly before storing or reusing
FAQs: Lightning Storm in a Jar
Can I use cold water?
Yes, but warm water works better for activating the fizz and spreading color.
Is this safe for little kids?
Totally safe with supervision! Use plastic jars for toddlers and always supervise when using small parts like tablets.
Can I reuse the same oil?
Yes! Just refresh the water and colors if they get too muddy.
What if I don’t have glow paint?
No worries! A simple flashlight adds a fantastic lightning effect on its own.
