Exploring nappies

Science Club looked closely at nappies this week. Some brands of nappy cost three times the price of the supermarket own-brands. But do they absorb 3 times as much liquid? We set about investigating this.

We compared how much liquid each type of nappy could hold, by placing the nappies in trays of colourful alien wee.

Surprisingly, the supermarket nappy was just as good as the more expensive brand!

Both nappies could hold a lot of liquid, because they contain small granules of “Super Absorbent Polymers” which can absorb lots of water.

We took the nappies apart and had fun handling the squishy contents.
