poor little guy; i really do hope that things go well for them!

instead of vodka, use m. spirits. Its actually one part spirits to ten parts water. When frozen it has the same jelly sort of texture and is one of the safer options to use. Add a couple of drops of food colouring to them and seal zip lock bag, place in second bag, seal and then freeze.
They work well in this house anyhow! Great for big and little kids!
