it dissolves into the water that's why after a couple of minutes it's completely gone
When water is added to salt (NaCl), the salt will dissolve in the water, making a homogeneous solution.

sand salt
The flakes of gold are more dense than water, therefore, it will sink to the bottom and then the water can be carefully poured out
As salt is soluble in water, mixing salt and sand in water would result in solid sand, and salt water. When poured through a coffee filter, the sand would remain in the filter, while the salt water would flow through. After letting the water evaporate, salt would remain. You will be left with the two separated solids.
Can you explain why the coin was seen when water was poured into the cup?
When salt water is poured into a glass containing cold tap water, the salt water will collect and settle at the bottom of the glass. This is due to the salinity and density of the salt water.

Water would move OUT of the snail and onto the salt.
