How do people make themselves sink in water?

Question

I wanted to know if anyone can explain how people can make themselves sink when they are swimming and how i could learn to do it myself. I have read that it might be a matter of body size, but i have seen both thin and bigger people be able to make themselves. i have a friend who can float and sink when he wants. he's not sure how he does it, he just knows he can do it.

Answer 1

Do you know how to pencil dive? If you do this position in the water and release all the air out of your lungs you will sink. At least that's how i sink.

Answer 2

sinking is actually pretty hard my grandpa can do it really well and i kind of can but he always explains it as u have to take a big breath of air and go under water (w/o pushing down or anything) and u start blowing tons of bubbles out of ur mouth the hard part is that u have to blow all of the air out so if u dont practice it can hurt ur chest a little bit plus when u get down there u dont have any air stored but my grandpa can stay under there for like 2 min. so if u practiced letting all of ur air out and do breathing exercizes youll be able to do this longer- hoped this helped

Answer 3

Alls you have to do is exhale all of your oxygen  and your body will sink if you want to float take a big breath
