Cut flower shapes out of coloured paper. You can use a template like this one or just use your imagination. In the centre write a little positive message. It could be a thank you to someone or maybe a little promise or a prayer if you wish. Then fold the petals into the middle making sure the flower is flat. Gently place the flower on to the surface of water in a large bowl and the watch the petals open, revealing the message.
The kingdom of God is like a tree,
Growing through all eternity,
In its branches, bird may nest,
In its shade we all may rest.
