CrunchLabs Elephant Toothpaste Blast Science Kit by Mark Rober — 6 Blasts, Adjustable

The CrunchLabs Elephant Toothpaste Blast is a repeatable backyard science kit by Mark Rober that creates controlled foaming eruptions over 15 feet high for hands-on engineering play.

Bring viral-grade experiments into your yard with a kit designed to teach cause-and-effect, flow control, and basic reaction chemistry. This set reimagines the famous elephant toothpaste demonstration into a safe, supervised activity for kids, including an adjustable nozzle, six kit-powered blasts, safety goggles, and QR-guided lessons from Mark Rober. It emphasizes iterative testing: change one variable, observe the result, and try again.

How dramatic are the eruptions and how do I control them?

The kit is engineered to produce towering foam columns — the tested setup can launch foam beyond 15 feet (4.57 meters) when assembled and operated as directed. Control comes from an adjustable nozzle and simple tweaks to flow and timing, letting kids experiment with scale safely under supervision.

• Adjustable nozzle for flow-rate tuning
• Kit components sized for large single blasts
• Repeatable protocol for consistent comparisons
• Safety goggles included to protect eyes during demonstrations

What’s included and how many times can we perform the experiment?

Each package contains enough kit-supplied reagents and hardware to complete six full powered demonstrations right out of the box. After those six kit blasts, you can continue performing the experiment using common household ingredients following the same procedures and safety steps.

• Six kit-powered blasts included
• Reusable nozzle and mixing hardware
• QR code to access Mark Rober’s step-by-step video guides
• Instructions for performing more experiments with ordinary home supplies

Is this safe for kids and what supervision is required?

The toy is designed for supervised, hands-on learning: it includes protective eyewear and clear instructions to minimize risk. Adult supervision is required during setup and activation to manage the reaction and ensure safe distance for observers.

• Safety glasses included in every kit
• Clear, adult-directed setup and operating steps
• Outdoor use recommended for blast experiments
• Easy-to-clean foam residue and simple post-demo cleanup

How does this kit teach science and engineering skills?

Beyond the spectacle, the kit is structured for iterative investigation: kids change variables, measure results, and form hypotheses about cause and effect. QR-linked tutorials from Mark Rober walk through the engineering mindset, explaining why results change when you alter nozzle position, reaction timing, or ingredient amounts.

• Experiment prompts that encourage hypothesis testing
• Video walkthroughs that explain the why behind each step
• Opportunities to record and compare outcomes across trials
• Hands-on tuning of flow and reaction parameters

Who is this for? CrunchLabs Elephant Toothpaste Blast is built for curious kids, families, and classroom groups who want a high-impact, repeatable science experience that blends engineering play with measurable results. It’s ideal for ages that can follow adult-supervised lab instructions, for parents and educators seeking a memorable STEM activity, and for anyone who wants a dramatic outdoor demonstration that motivates further scientific exploration.
