I did another stupid thing!
I bought some bouncy eyeballs in the Halloween section of the drug store and put them inside the IceOlogy clear ice ball maker.
The balls float inside the ice ball molds so when they freeze they're touching the outside of the ice ball- I'd prefer them to be fully enclosed in ice. Because the balls are not food safe I would not recommend serving these to customers in a bar setting, and because they touch the outside of the ice I'd not recommend serving them in alcohol, lest it degrade the plastic.
But anyway, another fun ice project for home. If you liked this, you might also enjoy these Spiders and other Insect Ice Balls I did last year.
