Creative cake decoration ideas?

Question

I'm making a hawiian cake for a school function and i'm doing the ocean and i was wondering if there is something that looks like water but is cheap or easy to make and not to messy, thanks, any other ideas are welcome also!

Answer 1

All the cakes I've seen showing water just used blue coloring in the normal frosting.

Answer 2

You can also use piping gel. Color it blue, or put it over already blue

icing. You can buy it any cake decorating store, Michael's, Joanne's

or Walmart.  

Answer 3

Use blue icing and put it in a zip lock bag squeeze it and you can mke waves with it. To make it come out thinker make the hole larger.

Answer 4

Make a thin sheet of blue Jello. Nake it a little stiff by not using as much water in the recipe.
