How to make is almost the same as the Brain Soda I wrote before. The difference is just brain or eyeballs. But my opinion is eyeballs are much easier to eat than brain.
1: Use rice-cake powder and make a dough. And then separate the dough to big white dough, green small dough with green food coloring and tiny tiny black dough with black food coloring.
2: Make eyeballs. (Make white ball and stick green with black dot sheet)
3: Pour clear soda like 7up to a glass and add red food coloring and make red soda.
4: Put the eyeballs in the glass.
