Instead of blowing directly into the small opening, she waves the bag through the air, letting it scoop in a huge volume at once. Bernoulli’s principle explains that fast-moving air creates a low-pressure zone, which pulls in surrounding air and fills the bag rapidly. With just a few sweeps, the sleeping bag is fully inflated, showing how physics can make a s
