My conclusion is that Rootbeer has the most sugar.(I added 1/2 of a cup of salt to the bucket.)
Then Coke.(I added 1/3 of cup of salt to the bucket.) Tied for third place is Sunkist and Sprite.
( I added 1/4 of a cup of salt to the bucket.)Then was Nestea and Diet Coke. (I added no salt to
the bucket.)That means if you’re having any Pop at all you should have Nestea because in Diet
Coke there is something called Aspartame which is also not good for you. So, you should have
no soda at all because of the sugar, caffeine, and the harm it does to your teeth.

Why the pop cans floated to the top when I added salt?

When the density of the water is more than the pop can, then the pop can will float to the top.
I increased the density of the water by adding salt and mixing the salt in the water intil the
salt dissolved. When salt dissolves in water the density increases. The more salt that is
dissolved in the water the greater the salt water density will be. Density is mass per
unit of volume. When you dissolve the salt in the water the mass will be more but the volume
is going to be the same. That means the density is going to be different.
