3. Mache Wasser glitschig durch flüssige Seife

• Turning their bottle bottom up they observe that water does not flow out Photo 1: see white and black arrows.
• After shaking they succeed in getting rid of the water.
• To learn about the effect of detergents children are given "magic water" (for the youngest), "soap", washing-up liquid.
• Now the water is easily flowing out, leaving air bubbles inside the bottle.
• Soon the first child starts to use the syringe as a pump: Air bubbles are comming out of the water.

Others shake the bottles producing foam.
