All you do is put a few drops of food
coloring in a balloon, fill it up with water and then set them
outside to freeze. After they are frozen, you pop the plastic
and see what you have.
We also are making
ice luminaries but will have to wait until dark to see how they
look.
We also wanted to make
these ice
sculptures (scroll down to the bottom) but didn't have the right
long and skinny balloons here at the house so we'll have to try
these another time. They're so cool looking!
