National Geographic Gross Science Kit — Kids STEM Kit

Intro

National Geographic’s Gross Science Kit from Blue Marble (model NGMEGAGRS) is designed to be a loud, silly, and educational box of hands-on experiments for kids. The listing describes a set that includes everything needed to perform 15 built-in "super gross" chemistry experiments and a bonus booklet with a further 30 experiments using household items — together adding up to the "45 gross" experiments called out in the product title. The kit is pitched as a STEM activity for kids and is tied to National Geographic’s educational mission; the listing and owner feedback highlight that the instructions are kid-friendly, illustrated, and that the experiments teach basic concepts like polymer behavior, pH, phosphorescence, and simple biology.

What it is / first look

At first glance this is a compact, all-in-one science kit marketed under the National Geographic sub-brand and manufactured by JMW Sales, Inc. The listing lists the product as a "Super Gross Chemistry Lab" and says the box contains everything needed to perform the 15 headline experiments, plus a bonus experiment guide with 30 additional activities that use common household items. The package dimensions are listed at 11.81 x 8.66 x 3.15 inches and the item weight is listed as 2.1 pounds — small enough to unwrap and store on a shelf between sessions.

The product is presented as a hands-on STEM toy that leans into gross-out themes: the listing explicitly describes experiments that include boiling boogers, creating glowing worms, making a test-tube vomit, dissecting a squishy brain, and making atomic pee and farting slime. The kit is described as delivering lessons on polymers, chemical reactions, pH science, phosphorescence, and biology through those playful projects. The listing also emphasizes that no batteries are required and that the kit is for ages 8 years and up.

Who this is a good gift for

Be specific when matching this kit to a kid — the product leans on gross-out appeal and hands-on chemistry. Below are practical recipient fits and the assumptions that make each a good match.

The gross-and-curious kid (ages 8–12)

• Why it fits: The listing’s experiment examples — boiling boogers, glowing worms, test-tube vomit — are the exact draw for kids who love silly, icky science. Owner feedback repeatedly notes that kids who like "gross" experiments were fully hooked.
• What must be true: The child should be comfortable with messy or yucky themes and be at or above the manufacturer-recommended age (the listing states 8 years and up).

The budding STEM kid who likes demos

• Why it fits: The kit is framed around clear science topics — polymers, pH, phosphorescence, chemical reactions, and biology — presented with kid-friendly, illustrated instructions (per the listing). That makes it a practical introduction to these ideas without needing a full lab setup.
• What must be true: The recipient should enjoy guided experiments rather than abstract worksheets; the kit supplies and an illustrated guide are central to the experience.

The family that does science together

• Why it fits: Multiple owner reports describe the kit as a family activity that keeps kids entertained and curious. Buyers mention spending quality time with kids and grandkids while running experiments.
• What must be true: An adult will be available to supervise the messier or higher-step experiments (the listing’s experiment descriptions include boiling and dissection-style projects).

A teacher or homeschooler looking for classroom demos

• Why it fits: The box is compact and the listing promises a variety of experiments plus a bonus booklet with household-based variations — handy for repeating demos without additional spending.
• What must be true: The educator should check quantities — the listing states it includes everything needed for 15 experiments, but the item page does not list every tiny component in the box.

The budget-conscious gift buyer

• Why it fits: The kit is explicitly promoted as a full set of engaging experiments with both in-box activities and extra ideas using common household items — an economical way to gift a multi-session learning toy.
• What must be true: The giftee should be the right age and temperament for novelty-style gross science rather than looking for advanced lab-grade materials.

In daily use

Owner feedback and the listing paint a picture of short, repeatable experiments that are easy to follow and designed to keep attention. The listing says experiments don’t take too long, and owners consistently report that the activities hold kids’ attention for hours across multiple sessions.

How a session typically looks: an adult or older kid reads the illustrated step-by-step instructions, prepares a few simple items, performs the reaction or activity (slime, glowing worms, vomit-style bubbles, etc.), and then reviews the brief science notes provided in the guide. The bonus booklet with 30 additional experiments is attractive because it stretches the value of the kit: owners say the extra guide uses household items so kids can experiment again without exhausting the in-box supplies immediately.

Practical notes from owners: instructions are described as easy to read and accompanied by images, which keeps younger experimenters engaged. Several buyers mention it’s a great "one-and-come-back" gift — not just a single-use toy — because the range of experiments and the ability to repeat or vary them keeps kids returning to the box.

Materials & build quality

The listing describes the product as a "high-quality hands-on science toy" — a manufacturer claim that’s reiterated in the product copy. The included-components statement reads as "Everything you need to perform 15 super gross experiments," but the listing does not enumerate every small item or chemical by name on the product page.

Owner experience confirms a generally complete kit: multiple buyers say the set "brings everything you need" and that they didn’t have to run out for many extra supplies to complete the experiments. That recurring owner note is good evidence the box contains the core materials required for most of its headline projects.

Physical fit: the kit is compact (11.81 x 8.66 x 3.15 inches) and weighs 2.1 pounds, so it’s easy to store and move between the kitchen and a work surface. There’s no claim in the listing about premium lab-grade glassware or heavy-duty components — this is a children’s educational kit with disposable or simple reusable supplies intended to teach concepts rather than serve as lab equipment.

Safety considerations

Start with what the listing states: the kit requires no batteries, and the experiments listed in the product copy include boiling boogers, dissecting a squishy brain, making test-tube vomit, and other activities that involve chemical reactions, heating, or simulated dissection. Because those activities can involve heat or small parts, plan adult supervision and a safe, easy-to-clean workspace.

What the listing does and doesn’t specify: it explicitly calls out the gross experiments and the scientific topics covered (polymers, chemical reactions, pH, phosphorescence, biology), but the product page does not list a formal set of safety certifications or a detailed component-by-component hazard list. The listing also does not provide a printed age-supervision policy in the product copy shown. For parents and teachers, the repeated owner pattern is instructive: many buyers ran activities together with kids rather than leaving children unattended, and several praised the instructions as clear enough for guided parent-child experiments.

Practical safety suggestions tied to the listing’s content:

• Plan adult supervision on experiments that the listing describes as involving heating (the listing mentions "boiling"), sharp tools used for a "dissection" activity, or strong reactions.
• Use a washable surface and protective coverings — the kit’s theme involves goo and slime and is described as messy by construction in the product copy and in owner feedback.
• Confirm the component list before gifting (see checklist below) so you know whether small, swallowable items are included; the listing does not enumerate each small part.

Who should skip it

• Children under the manufacturer recommended age: the listing states the kit is for ages 8 and up. If you’re shopping for a toddler or preschooler, this is the wrong fit despite a single owner mentioning that kids as young as 2 watched along — that report is an exception and not a manufacturer endorsement.
• Kids or adults who are squeamish about gross themes: the kit intentionally trades on yuck and gore-adjacent experiments. If the recipient dislikes that humor or sensory territory, it will disappoint.
• Parents who need a fully itemized parts list or lab-grade materials: the listing promises everything needed for the 15 main experiments but does not list every chemical or small component on the product page. If you require complete ingredient transparency, this listing is lighter on those details.
• Gift givers who want a high-end, presentation-ready gift: the product is a compact activity kit, not a luxury boxed set; the listing doesn’t emphasize gift packaging beyond the standard boxed product.

Verdict

Bottom line: this is a friendly, budget-oriented STEM kit with a clear niche. The product page and owner feedback align: the kit pairs a collection of 15 ready experiments with a 30-project bonus booklet so kids can repeat and adapt activities using household items. The instructions are consistently reported as easy to follow and illustrated, and multiple buyers mark the kit as a hit for keeping kids entertained and curious about science.

Gift recommendation: buy for an 8–12-year-old who likes hands-on, silly science and will have an adult nearby to run the more involved activities. It’s a practical, engaging gift for families, classrooms, and STEM-curious kids — a safe casual pick rather than a premium lab investment.

Check before you buy

• Confirm the current listing’s included components if you need a full parts inventory — the product page promises "everything you need for 15 experiments" but does not itemize every small component on the page.
• Verify the recipient’s age and temperament: the listing states "8 years and up" and the subject matter is intentionally gross.
• Plan for adult supervision for the experiments described as involving boiling or dissection-like steps, and pick a washable workspace.
• Keep household basics on hand for bonus experiments — the listing’s extra 30 experiments rely on common household items.
• Decide whether the recipient wants novelty/gross themes or a more serious STEM kit — this skews playful and novelty-driven.

Colors and packaging note

The listing does not present multiple colorways for the kit; the product is sold as a boxed activity set with printed packaging. Available colors may include only the default packaging artwork — the listing does not specify separate color options.

Final gift pick guidance

If you’re shopping with gift intent: this is a strong, low-risk buy for an 8–12-year-old who likes hands-on, messy, playful science. The kit’s combination of manufacturer-backed branding (National Geographic sub-brand, Blue Marble), an illustrated instruction guide, and owner praise for being engaging and educational make it an easy pick for parents, grandparents, and teachers who want a budget-friendly STEM present that also leans into novelty. If you need detailed part lists, certification detail, or a non-gross approach to science education, consider a different kit that lists every component and safety certification up front.
