Bubbly Volcano Song: How CO₂ Pushes Foam

◷ 2:19

A lively children’s song reveals what happens when baking soda meets vinegar: carbon dioxide gas, or CO₂, forms and pushes foam from an open bottle. Dish soap only traps the bubbles; it does not make the gas. Try it with a grown-up, on a tray, away from eyes, and never drink the mixture.

Text from the recording’s subtitles.

Song lyrics
ماذا يصحو في جبلنا الورقي؟ مع شخص بالغ، ضع المخروط فوق صينية وفيه زجاجة بلاستيك مفتوحة اسكب فيها خلًا ملوّنًا ثم قليلًا من سائل الصحون أضف الصودا للخل فيتفاعلان يأتي الفحيح، وتكبر الفقاعات الصودا والخل يصنعان غازًا ثاني أكسيد الكربون، CO₂ يدفع هذا الغاز الرغوة للأعلى فتعبر حافتها وتنساب على المخروط سائل الصحون يحبس الفقاعات ويبقي الغاز محبوسًا فيها لكنه لا يصنع CO₂ فتكبر الرغوة حتى تفيض وتنحدر ألوانها فوق المخروط الصودا والخل يصنعان غازًا ثاني أكسيد الكربون، CO₂ يدفع هذا الغاز الرغوة للأعلى فتعبر حافتها وتنساب على المخروط تكشف الفقاعات غازًا تكوّن الآن هو من دفع الرغوة خارج الزجاجة تبدو كالحمم، لكنها فقاعات صابونية الصودا والخل كوّنا غاز CO₂ وذلك الغاز دفع الرغوة للخارج
Language version lyrics
What wakes inside our paper mountain? With a grown-up, set the tray below An open plastic bottle fits the cone Pour in vinegar bright with color Add a little dish soap too Tip in baking soda; now they react Hear the hiss; quick bubbles multiply Baking soda and vinegar make gas Carbon dioxide, CO₂ That gas pushes foam up past the rim Then it streams down the paper cone Dish soap catches every bubble And holds the gas inside its foamy net But the soap makes no CO₂ Gas-filled foam climbs over the rim Colored rivers run down the cone Baking soda and vinegar make gas Carbon dioxide, CO₂ That gas pushes foam up past the rim Then it streams down the paper cone Those bubbles show the gas just made It pushed the foam out of the bottle It looks like lava, but it's only suds Baking soda and vinegar made CO₂ That gas pushed the foam outside
