Items float on water when enchanted

Make a custom enchants that it can be put on chests!
than when we place it , and we put items in it , it will sell the items in the chest automaticly
thanks for your good server

Make it so that the mcMMO custom enchants are of different colors.
Perhaps Light Aqua?
That would be easier to look for mcMMO enchants if you have piles upon plies of custom enchant books.
And that it would add a variety to the enchants.
