You start with a small, flat lump of dough. A while later... it puffs up big and soft!
What makes it grow? There are no balloons inside! Let's become bread detectives and find out. 🕵️
Hidden in the dough are millions of yeast — living things SO small you need a microscope to see them.
Tap the dough to zoom in with the microscope 🔬
Yeast is alive — like a teeny pet. And like every pet, it gets hungry! 🍽️
Flour has tiny bits of sugar inside it. When yeast eats sugar, it wakes up and gets to work.
Tap the sugar cubes 🍬 to feed the sleepy yeast — feed all 3!
After eating, the yeast lets out a gas called carbon dioxide — like tiny invisible burps! 💨
Tap the happy yeast to make bubbles of gas. Make 5 bubbles!
Dough is soft and stretchy because of something called gluten — it works like a net of tiny balloons. The gas bubbles get trapped inside and puff the dough up.
Which one rises into bread? Tap your answer.
Stretchy dough holds the gas like a balloon. That's why we knead (squish) dough — it builds the stretchy net! 💪
Warmth makes yeast work faster, and the trapped gas puffs even bigger. Then the heat sets the bread firm — so it stays tall and soft.
Slide to turn up the oven heat and watch the dough rise! 🔥
You cracked the case! Tap the steps in the right order, from start to puffy bread.
Now you know the bread-rising secret:
No balloons needed — just hungry yeast making gas! Next time you eat soft bread, look for the little holes. Each one was a bubble of yeast gas. 🍞✨
