What happens if you belch in Antarctica?<\/p>\n

Truth is, part of it would freeze into a solid chunk.<\/p>\n

In our atmosphere, every gulp of air contains about 21% oxygen. With every breath you take in, your lungs transform about 20% of that oxygen into carbon dioxide.\u00c2\u00a0 Carbon dioxide freezes below -109 deg F, and in Antarctica, it can get below -140 deg F.\u00c2\u00a0 Dry ice, anyone?<\/p>\n

But you can make burp gas without using a kid.\u00c2\u00a0 Did you know that the bubbles formed from combining vinegar and baking soda are also carbon dioxide?\u00c2\u00a0 And when you crack open a fresh bottle of soda, that PSSST! is also carbon dioxide?\u00c2\u00a0 And the combination of mentos and soda gives you the same thing.<\/p>\n

What can you do with carbon dioxide? You can carefully fill a container with it and ‘pour’ the invisible gas over a lit candle the extinguish the flame.\u00c2\u00a0 You can make a balance and see which weights more – cup of ‘air’ (an empty cup) or a cup of carbon dioxide.<\/p>\n

What happens when you freeze the cup of air and cup of CO2?\u00c2\u00a0 Does that change the weight measurement?<\/p>\n

If you need more help, like how to pull together a written report and make a display board, be sure to visit our Science Fair Porject kits<\/a>.<\/p>\n

What else can you do?\u00c2\u00a0 Have fun!<\/p>\n","protected":false},"excerpt":{"rendered":"
