Gelatin Bubbles

Gelatin Bubbles look great on cakes! Those can be made in various colors and luster dust can be mixed in to give it some character and shine.

This tutorial by Cake Ball Love is quite detailed and would be a good resource if you want to try making these amazing bubbles. Seven Clown Circus also has a good tutorial.

This is how mine turned out.

These were made just for practice but I plan to try those for a cake sometime.
