I have seen these ice lanterns at friends parties in years past and want to attempt to make some.
It sounds pretty straight forward. Take a latex ballon and fill with water. Then place in freezer for 4-10 hours depending on the size. You can put them outside if the weather is much below freezing. When frozen cut away ballon and drain water. Place tea light in and voila.
I have one friend who added food coloring to hers but it does make a bit of mess when melting but a very neat idea. I wonder whst glitter or fruit would do to them?!
Anyone tried this yet?
