How Food Becomes You
🍞 How does the food we eat become part of our body? Large nutrients can't enter as they are! Count the pieces to find the pattern: saliva breaks down starch, gastric juice digests protein, and fat is only broken down in the small intestine. 🌾 The inner wall of the small intestine is folded with villi, expanding its area by 600 times! There are two paths: glucose enters capillaries, while fatty acids go into lacteals to avoid clogging blood vessels. ❤️ Finally, we reach the heart! What separates arteries from veins is direction, not oxygen level. Explore and see for yourself! Built with code — why not remix it to add breathing too?
Static and Flowing Electricity
⚡ Hair sticking to a comb isn't creating new electricity! Electrons just moved from one side to the other, so the total charge is always 0. 🧪 Glass is fascinating: rub it with silk and it becomes positive, but rub it with fur and it becomes negative. The charge sign depends on the pair, not just the object! 🎈 Play with two balloons by changing their charges and distance to see how charge is proportional while distance works by inverse-square. 🔄 Finally, move a magnet in and out of a coil to generate current. Hold it still inside? Current drops to 0 — change creates current, not presence! Built with code · Remix it to add your own generator!
