Question

why does aluminium foil vessel slot and the folded foil sink​

Answer 1

Answer:

The density of aluminum is 2.7 g/ml. The density of water is 1 g/ml the air trapped in the ball and the foil boat makes the density of the metal boat less that 1 g/ml. so the boat and ball floats. When you remove the air from the foil ball the density of the foil becomes more that 1 g/ml so the foil now sinks.
