{"product_id":"1-set-water-tornado-swirl-maker-wooden-puzzle-novelty-science","title":"DIY Water Tornado Swirl Maker — Wooden Vortex Science Experiment Kit","description":"\u003cp\u003eFill the two chambers with water, spin the connector, and a stable vortex forms between them — a visible, repeatable demonstration of centripetal force and angular momentum that kids can control by hand. The wooden frame holds the chambers at the correct angle for consistent vortex formation. Works with plain water; no chemicals or batteries required. \u003cstrong\u003ePrice: $12.\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVisible centripetal force demonstration\u003c\/strong\u003e — water spirals inward toward the central axis as it drains, showing how centripetal acceleration keeps fluid in circular motion rather than falling straight down\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAngular momentum in action\u003c\/strong\u003e — the vortex sustains itself as long as rotation continues; kids can vary spin speed to observe how angular momentum affects vortex stability and diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWooden frame construction\u003c\/strong\u003e — laser-cut wood holds the two water chambers at the correct alignment; durable enough for repeated classroom use and science fair demonstrations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo batteries or chemicals required\u003c\/strong\u003e — runs entirely on water and manual rotation; safe for all ages and easy to reset between experiments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRepeatable experiment setup\u003c\/strong\u003e — drain, refill, and spin again; consistent results make it suitable for structured observation and data recording in classroom settings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCovers grades 4–8 physics topics\u003c\/strong\u003e — fluid dynamics, vortex formation, centripetal force, and gravity — aligns with standard middle school science curriculum\u003c\/li\u003e\n\u003c\/ul\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhysics Topics\u003c\/td\u003e\n\u003ctd\u003eCentripetal force, angular momentum, fluid dynamics, vortex\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eWood + plastic chambers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Required\u003c\/td\u003e\n\u003ctd\u003eNone (manual rotation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChemicals Required\u003c\/td\u003e\n\u003ctd\u003eNo (water only)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrade Level\u003c\/td\u003e\n\u003ctd\u003e4–8 (ages 9–14)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUse Case\u003c\/td\u003e\n\u003ctd\u003eClassroom demo, science fair, homeschool STEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrice\u003c\/td\u003e\n\u003ctd\u003e$12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"AliExpress","offers":[{"title":"Tornado model \/ China Mainland","offer_id":53717345534136,"sku":"TORNADOMODEL-CHINAMAINLAND","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0937\/3764\/8312\/files\/Sac9a05f9aa4a49f2b65a34d835c25e1e7.webp?v=1783486004","url":"https:\/\/hardassetsecurity.com\/products\/1-set-water-tornado-swirl-maker-wooden-puzzle-novelty-science","provider":"Hard Asset Security","version":"1.0","type":"link"}
