Spin casting

Spin casting is like making a copy of something using a special machine. The machine is like a big bowl that spins really fast.

First, we take something we want to make a copy of, like a toy car or a ring. We cover it with a special putty called silicone, which makes a mold of the object.

Then, we mix together a liquid that will become the copy of the object. This liquid has special things in it that make it harden when it touches air.

We pour the liquid into the machine and turn it on. The machine spins really fast, and the liquid gets pushed outwards by the spinning. This makes the liquid go into all the tiny spaces of the silicone mold we made earlier.

We wait for the liquid to harden, which usually takes a little while. Then, we open the machine and take out the copy of the object we wanted. Voila! We have a perfect copy of our object.
