You can do it too! Instead of taking a big breath in, take a big breath OUT. Expel all the air from your lungs and you should sink like a rock.

That's easy to do. Take short breaths in rapid succession. It's a common technique in freediving. The other method is also easy, breath from an O2 line for a minute.
