Mystified by the amount of water a single diaper can hold?
If you've got a few extra diapers laying around after last week's experiment, consider dissecting one and to learn what's inside.
You'll need a diaper, a pair of scissors, and a zip-top bag. You may also find it convenient to work over a black piece of paper.
Begin by cutting a slit in the diaper.
While shaking, the crystals should separate from the cotton and settle at the bottom for the bag.
Again, it could be interesting to compare the crystals found in different brands of diapers - are they all the same size, do they come in the same quantity?
A good scientific exploration to learn more about the world around us, and also an introduction to polymer chemistry!
