Resources required:
An empty water bottle; a small piece of fabric e.g. a towel or an old sock; liquid soap; water; food colouring; rubber band; scissors; glycerine (optional).

Description of investigation:
To make the bubble solution pour 2 to 3 tablespoons of liquid soap in a bowl and mix with 250ml water. You may add glycerine to have stronger, longer lasting bubbles. Stir well.
Cut the bottom of an empty, clean plastic bottle using scissors.
Cover the cut opening with the fabric and secure with a rubber band.
Add a few drops of food colouring to the fabric at the end of the bottle.
Dip the fabric covered end in the bubble solution.
Blow into the mouth of the plastic bottle.

Investigation Questions:
What shape are bubbles?
Does blowing hard or soft effect the shape of bubbles formed?
How are so many bubbles formed at once?
