10 totally gross experiments — real chemistry, real reactions, real disgusting fun
Every experiment has a genuine chemical explanation — polymer cross-linking, phosphorescence, acid-base reactions, non-Newtonian fluids. Kids think they're being disgusting. They're doing real chemistry.
The gross factor isn't a gimmick — it works. The emotional response to something disgusting makes the science far more memorable than a textbook exercise. First they laugh. Then they ask why it happened.
The full-colour illustrated guide doesn't just tell you what to do — it explains why it works. After dissecting a brain-shaped gel, kids learn what agar agar is and why heat causes it to set.
The 10 core experiments use the kit's included chemical compounds. A separate bonus guide adds 10 more using everyday household items — extending the fun well after the kit chemicals run out.
This kit uses actual chemical compounds — sodium alginate, calcium chloride, agar agar, zinc sulfide, phenol red. When your child drops sodium alginate into calcium chloride and watches it form a wobbly eyeball, that's spherification: the same technique used by Michelin-starred chefs in molecular gastronomy. The guide teaches the name, explains the reaction, and connects it to the real world. Gross is just the gateway.
10 completely gross chemistry experiments — all materials included
Mix, measure, pour, and observe. Each experiment uses the included chemicals and equipment — no extra shopping required.
A chemical reaction sends foam erupting out of a test tube in an unmistakably vomit-like overflow.
Learn: Acid-base reactions, carbon dioxide gas production
Drop sodium alginate solution into calcium chloride and watch it skin over into wobbly, squishy eyeballs.
Learn: Spherification, polymer cross-linking
Mix agar agar to set a brain-shaped gel mould, then peel it out and dissect it like a real specimen.
Learn: Gels and colloids, basic biology
Mix zinc sulfide into an alginate solution, shape it into worms, and watch them glow green in the dark.
Learn: Phosphorescence, polymer shaping
Use the phenol red pH indicator to make colour-changing 'pee', then add bicarbonate for gas-releasing slime.
Learn: pH indicators, acid-base science, gas reactions
Use chemical reactions to simulate cell rupture in a liquid medium — complete with satisfying colour change.
Learn: Cell biology, osmosis, polymer reactions
Plus Glorious Guts, Boiled Boogers, Goo Defying Gravity, and Bubble Goop Swamp — all 10 inside the kit!
20 experiments, real chemical compounds, and the science behind every reaction — the grossest chemistry set your child will ever love.
