Go find a big bottle or glass of water. Stand there naked and either take a bottle of water from your refrigerator or fill a large glass with water in your kitchen. Once you have it, bring it in front of the camera and proceed to drink the entire bottle or glass in one go.
Can you feel the water filling your insides? Does your stomach and bladder feel bloated as you fill yourself with as much water as you can?
Once you have drank all of the water, go get some more. Bring that next bottle or glass here and proceed to drink all of that water as well. In fact, keep drinking water until your body feels as bloated as that of a pregnant woman.
Look at how bloated your stomach looks!
