{"product_id":"cloud-apparatus-glass-flask-with-bulb","title":"Cloud Apparatus, glass flask with bulb.","description":"Demonstrate the principles of cloud formation even when there isn't a cloud in the sky with the Cloud Forming Apparatus. When the atmospheric pressure is lowered in the chamber and smoke particles are introduced into the flask, a nucleus for the formation of water droplets is produced. When the bulb is compressed and then suddenly released, a cloud is formed inside the flask.  This is a fun STEM demonstration for an earth science or a physics classroom. Instructions are included.","brand":"GSC International","offers":[{"title":"Default Title","offer_id":49507500065045,"sku":"GSC4-30101","price":21.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/4-30101.jpg?v=1761839143","url":"https:\/\/unitedsupplycorp.com\/products\/cloud-apparatus-glass-flask-with-bulb","provider":"United Supply Corp.","version":"1.0","type":"link"}
