Rebar
Okay kiddo, do you see how we build towers, bridges, and other big structures using long and heavy metal bars that are joined together tightly? Well, these metal bars are called rebar or reinforcing steel.
The main job of rebar is to make these structures stronger and capable of holding a lot more weight, just like how superman gets stronger when he wears his cape! Rebar is made up of steel and has ridges on it that helps it to stick better with the concrete that is poured around it. This way, the rebar and concrete work together, making the structure tough and able to handle heavy loads without breaking.
So next time you see a big building being constructed or a bridge being built, you can know that the rebar is playing a very important role in making it strong and safe!
