Explaining the Holy Trinity to children

One way which I have found helpful to describe to children how God reveals Himself to us in the Holy Trinity is that:
God the Father is the mouth.
The Word He speaks is Jesus the Son.
And the breath He uses to speak is the Holy Spirit.

The Father is the idea.
The Son is the Word telling about the idea .
And the Spirit is the action that puts the idea into practice.

Tell children to think of a word.
Then holding their hand in front of their mouth, speak the word.
The "thought" I compared to the Father.
The "spoken word" I compared to Jesus Christ, the Son of God.
And the breath they felt on their hand, I compared to the Holy Spirit, the breath of Life that carried the spoken word out.

Take 3 strands of string (3 different colours if possible).
Braid them together for about half their length and stick this onto a piece of card. Then separate out the 3 strands and stick them down separately.
The 3 strands braided together represent God as one.
And then each strand can represent Father, Son and Holy Spirit.

The Trinity is like an ice cube in a pan of boiling water.
The ice is solid, the water is liquid and the steam is gas but they are all H2O.
All three things are separate, but they are all the same thing and all at the same time in the same place.
