With this cloud chamber, you can see them.\u003c\/p\u003e\u003cp\u003eA diffusion cloud chamber maintains a supersaturated alcohol vapour layer just above a cold surface. When a charged particle — an alpha particle, beta particle, or cosmic ray muon — passes through, it ionizes the vapour and leaves a visible white trail, exactly like a jet contrail but at the subatomic scale. You are watching individual particles from outer space.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat you see:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStraight, thick tracks\u003c\/strong\u003e — alpha particles from natural radioactive decay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurved, thin tracks\u003c\/strong\u003e — beta particles and electrons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong straight tracks\u003c\/strong\u003e — cosmic ray muons passing through from space\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForked tracks\u003c\/strong\u003e — particle collisions and decays\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e Acrylic chamber · Peltier cooling element (no dry ice needed) · Power supply · Isopropyl alcohol · LED illumination · Instruction guide\u003c\/p\u003e\u003cp\u003eThe same technology used in the discovery of the positron, the muon, and kaons.\u003c\/p\u003e","brand":"Golden Physics Project","offers":[{"title":"Default Title","offer_id":54140237218084,"sku":"GPP-CLOUD-CHAMBER","price":149.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2879\/9524\/files\/92-7031ThermoelectricCloudChamber-042048x2048.jpg?v=1780680352","url":"https:\/\/shop.goldenphysics.org\/products\/cloud-chamber-observe-cosmic-rays-radioactive-decay-in-real-time","provider":"Golden Physics Project","version":"1.0","type":"link"}
