Sand casting

Okay kiddo, have you ever played with sand at the beach? That's kind of like what sand casting is, but instead of playing with it, we use it to make things.

So, first we need to make a shape out of something called a "pattern." This is basically a model of what we want our final product to look like. We can use different materials to make the pattern, like wood or plastic.

Next, we take our pattern and press it down into sand. This makes an impression of our pattern in the sand, kind of like how you can make a handprint in the sand at the beach.

After we make the impression, we take the pattern out and pour in liquid metal or another material into the sand. The metal fills up the space where our pattern was, and then we let it cool down and harden.

Once the metal is cool and hardened, we break apart the sand mold to reveal our finished product!

Overall, sand casting is a way to make things out of metal or other materials by using a pattern to make an impression in sand and then pouring liquid metal into that impression to create a final product.
