Frigorific mixture

Okay kiddo, have you ever felt really cold before when you were playing outside on a winter day? Well, that's because it was really cold outside and your body started to feel chilly.

Now, imagine we want to keep something cold for a long time like ice cream or frozen vegetables. We can't just rely on the cold weather outside, so we need a special mixture called a frigorific mixture.

This mixture is made up of different things that help keep things cold, like ice, salt, and water. When you mix these things together, they create a lower temperature than just normal ice on its own.

So, we can put our ice cream or frozen vegetables in a container and surround it with this frigorific mixture to keep them nice and cold for a long time. Just like how your winter coat keeps you warm on a snowy day, this frigorific mixture helps keep things cold!
