Mini Volcano with LED Eruption
Mini Volcano with LED Eruption — A 555 Timer Pulsing Circuit That Brings Your Science Fair Volcano to Life
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine your child’s eyes widening as the volcano they shaped from newspaper and paint erupts not with mess, but with a fiery pulse of red and orange LEDs. This kit transforms the classic science fair staple into a real electronics project, where the 555 timer chip orchestrates a lifelike lava glow. No coding, no soldering — just the thrill of making something that lights up exactly the way a volcano should.
What You'll Build
A handcrafted paper mache volcano that comes alive with a pulsing LED eruption. Red and orange LEDs alternately brighten and fade, creating a flow effect that mimics molten lava spilling down the slopes. Once assembled, you’ll have a battery-powered display model that stands out at any school exhibition or home learning corner.
What You'll Learn
- How a 555 timer IC generates a square wave to make LEDs blink in sequence
- Connecting LEDs and resistors to control brightness and timing without soldering
- Reading a simple circuit diagram and placing components on a breadboard
- Blending art, craft, and electronics into a single hands-on STEM project

Who This Kit Is For
This project is tailor-made for young science fair enthusiasts in CBSE primary school classes (1–3) who want a dramatic, moving display. It’s also a brilliant entry point for ATL Tinkering Lab juniors and parents seeking a playful way to introduce electronics — right at the intersection of art, science, and hands-on making.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to talk to the AI companion — it knows every component in this kit. If you still need help, message us on WhatsApp and we’ll walk you through it.
Do I need extra supplies like glue or paint?
You’ll need basic craft materials such as newspaper, flour, water, and paint to build the volcano body. All electronics are included. The AI companion also shares a quick paper mache recipe.
Is this safe for a 6-year-old?
Yes. The circuit runs on two AA batteries and uses plug-in wires — no soldering or sharp tools. Adult supervision is recommended for the paper mache part, but the electronics are completely child-friendly.
Can this be used for a school science fair?
Absolutely. The pulsing LEDs create an eye-catching eruption effect, and the 555 timer is simple enough for young students to explain how it works. It’s a classic project that always earns top marks.
