General Science / Is a sealed, water-filled can of water denser in water than a similar empty can?

My friends and I watched a magic show where a magician tied him self to a jerry can full of water and jumped in to a lake.
I said that as the can contained only water and was been smudged in water the only 'real' weight to it was the can its self as the water inside has the same density as the water around it?
My friends think as it's a sealed can it is a single mass, like any 25kg weight and would sink to the bottom like a rock?
I obviously know the can would sink but I think only due to the the Wight of the can not the water inside?
Who is correct???
