Squash is kind of like a magical juice that you can make at home by mixing water with a special flavored syrup. The syrup comes in a bottle and you only need to use a little bit of it to make a big jug of squash.
Imagine you have a box of crayons and you choose your favorite color, like red or blue. The squash syrup comes in lots of different yummy flavors just like choosing your favorite color. Some popular flavors are orange, blackcurrant, and strawberry.
To make squash, you first need a big jug or pitcher, something that can hold water. Next, you add a little bit of squash syrup to the jug, just like adding some paint to a picture. Then you pour in water to fill up the jug, but not too much or the squash will be too weak.
To make squash even more fun, you can add ice cubes to make it cold and refreshing, just like when you play outside and need a cold drink. You can also add some slices of fruit, like lemon or lime, to make it look pretty and taste even better.
So to summarize, squash is like a special juice that you make at home by mixing water and a flavored syrup. You choose your favorite flavor, add a little bit of syrup to the water, and then add ice and fruit to make it delicious!
