Can a dead body explode?
So, an exploding corpse isn’t impossible, but it’s unlikely to happen during cremation because the body wouldn’t be allowed to reach the putrefaction stage; refrigeration or embalming can be used to slow decomposition until cremation.
How long does it take for a dead body to float?
Even a weighted body will normally float to the surface after three or four days, exposing it to sea birds and buffeting from the waves. Putrefaction and scavenging creatures will dismember the corpse in a week or two and the bones will sink to the seabed.
Do bodies float in water when dead?
As a general rule, yes. A cadaver in the water starts to sink as soon as the air in its lungs is replaced with water. Most dead bodies float this way, but there are exceptions. The smaller the limbs, the more likely a corpse will float facing up—short arms and legs create less drag.
Why do some bodies float and others sink?
As long as the water your body displaces weighs more than you do, you float. If an object or person has a greater density than water, then it will sink. If its less dense than water, then it will float. Density is determined by mass and the amount of space it takes up (its volume).
