Illustrate the generosity of Allah.
Put a few drops of liquid soap into a small container and fill with water.
Place the container onto a tray to contain the over spill.
Have the child blow one large puff using a straw submerged under the liquid and see how many bubbles it makes!
For every blow, the bubbles continue to multiply many times over.
We can not count Allah's blessings.
Allah tells us in the Qur'an that the more we thank Him from what He has given us, the more Allah will continue to give us!
