Change the colour of celery
Celery, water, glasses, food colouring, knife
Cut off the end of the celery, and stand in some water. Add a few drops of food colouring to the water, have a few different ones. Leave the celery until the end of the meeting. Look at the celery and see if it has taken up the water colour because of its construction.
