Steve Spangler's Geyser Tube Event Pack - Classroom STEM Kit (Pack of 10)

Turn your classroom into a hands-on science stage

Steve Spangler's Geyser Tube Event Pack gives educators a ready-to-run science demonstration that combines curiosity with clear, observable results. The kit includes 10 improved Geyser Tubes and candy packs, designed to fit standard 2-liter soda bottles. Students watch a dramatic geyser rise, with some bursts reaching impressive heights, while you guide the exploration safely with the built-in trigger mechanism.

What’s inside and how it works

• Ten improved geyser tubes built for durability and repeated use
• Mentos candy packs included for quick setup
• Designed for compatibility with common 2-liter soda bottles
• New trigger mechanism aimed to reduce accidental eruptions

The setup is simple and approachable: insert a bottle, add candies, and trigger the geyser with a safe release. Expect a visible reaction driven by gas buildup and rapid release, offering a memorable, sensory classroom moment without extensive prep.

Why it shines in classrooms, camps, and homeschooling

• Hands-on learning that engages multiple learners at once
• Durable, reusable components support ongoing projects, science fairs, and demonstrations
• Encourages experimentation by varying sodas or quantities to spark discussion on variables

Educators can use this pack to frame activities around inquiry and observation rather than simply following steps. The visuals—cloudy soda, fizz, and the visible geyser plume—provide a tangible context for discussing gas, pressure, and reactions, all while staying focused on safety and fun.

Who is this for and what to consider

• Ideal for classrooms, homeschool groups, camps, and science clubs
• Best used under supervision and with clear safety guidelines
• A cost-effective way to extend hands-on STEM learning over weeks or months

Notes: This pack emphasizes educational exploration and empirical observation. Outcomes can vary based on variables like soda type and bottle brand. Plan multiple trials to compare results and capture evolving questions from students.
