Hi, I’m Ken Kuwako, your Science Trainer. Every day is an experiment.<\/b><\/span><\/p>\n

That fizzy carbonated drink after a sports practice or on a hot day is simply the best! But everyone has had that disappointing experience: you put an opened bottle back in the fridge, take a sip the next day, and think, “…Ugh. It’s just sweet water.”<\/p>\n

To prevent this sad tragedy, there’s a clever gadget called the “Soda Fresh” or “Shuposhupo-kun” (a nickname meaning ‘pump-pump guy’). This brilliant invention attaches to the top of the bottle, allowing you to pump air in and increase the internal pressure, which stops the carbon dioxide gas from escaping the liquid.<\/p>\n

But did you know this handy tool is much more than just a soda preserver? It’s actually a powerful science machine that can create a “cloud” right inside the plastic bottle! Today, we’re diving into the dynamic scientific secret behind this “Shuposhupo” device: why it generates heat and how it allows you to make your own cloud.<\/p>\n

What’s Really Happening Inside the “Shuposhupo”? \u2014 The Moment Pressure Turns into Heat<\/h3>\n

First, let’s try an experiment: use the device to pump (pressurize) air into a plastic bottle. If you place a thermometer strip inside the bottle, and then pump vigorously, you’ll feel the bottle warm up when you touch it. Why does the temperature rise just from adding air?<\/p>\n
