“And early in the morning he came walking toward them on the sea. But when the disciples saw him walking on the sea, they were terrified, saying, “It is a ghost!” And they cried out in fear. But immediately Jesus spoke to them and said, “Take heart, it is I; do not be afraid.” Matthew 14:25-27

“Miracles, like those we read about in Matthew 14 are similar to parables. Both miracles and parables prompt much wondering. In the case of miracles, many people often wonder “Could this really have happened?”
“The principle that determines whether a body can sink or not is called Archimedes’ Principle. It states that, for a body to float, it needs to displace the exact same amount of water with a weight equal to the total weight of the floating body. The weight of the displaced water exerts a force on the body, causing it to float. This force is called buoyant force and we can change its value by changing certain characteristics of water.
“The condition for floating is quite simple: the buoyant force should be greater than or equal to the weight of the body. If the value of buoyant force is large enough, then a body floats; otherwise, it sinks. The only thing we need to worry about is how we can increase this buoyant force.
“So… How Can We Walk On Water?
