Pampers nappies are used for babies to absorb their urine. This is possible because the cotton of the nappies contains special small grains.
What you need
1-ml syringe filled with Red Sea water, Liquemin bottle with more sea water to refill the syringe, Pampers grains in a second Liquemin bottle.
Experiment
* Left: Ask an adult to open a Pampers nappy for you above a tray and to transfer the grains into a
   Liquemin bottle.
* Middle: Observe how a syringe is properly filled with the right quantity of water.
* Empty the syringe in drops into the bottle.
* Add as much water as the Pampers grains can soak up.
Observation
* Right: 6 syringes of water have disappeared in the bottle while a jelly pours out of it.
