Life vest

A life vest is like a big, puffy jacket that you wear when you go swimming or boating. It helps you stay afloat in the water and not sink down to the bottom. It works by trapping air inside the vest, which makes you buoyant, or able to float on the water.

The life vest is usually made out of a material that is waterproof, so it won't get heavy when it gets wet. It also has straps and buckles that you can adjust to make it fit snugly around your body. This is like wearing a seatbelt in a car - it helps keep you safe and secure.

If you fall into the water while wearing a life vest, you should try to stay calm and hold onto the straps so you don't lose the vest. The vest will keep you afloat until someone can come and help you out of the water.

Remember, wearing a life vest is very important when you are near water, especially if you don't know how to swim well. It's always better to be safe than sorry!
