When you blow up a balloon and keep blowing, it gets bigger and bigger. If you blow too much air, the balloon pops! That’s like an explosion. An explosion happens when something has too much energy inside and it bursts out suddenly. It’s like when you shake a soda can really hard, and then open it. The soda sprays everywhere because the bubbles inside want to get out all at once.
Think about popcorn. When you heat the corn kernels, they have water inside that turns into steam. The steam builds up pressure until the kernel can’t hold it anymore and pops into fluffy popcorn. That’s a tiny explosion!
Imagine a jack-in-the-box toy. You turn the handle and it plays music. Suddenly, the lid flies open and a clown jumps out. The clown is like the energy waiting to burst out.
In nature, a volcano is like a big mountain with hot, melted rock inside. When the pressure gets too high, the volcano erupts, and the hot rock bursts out. This is a powerful explosion!
