So after days of being stuck inside because of sick children and bad weather I decided we needed a fun activity. This is so easy and honestly they turn out beautiful. Fill balloons with water and a couple of drops of food coloring. Set outside to freeze.
I was thinking it would only take a few hours, over night at the most. It took several days and that was with below zero temps.
We then brought them in and pulled off the balloons. That was it, they were beautiful.
