Today we have investigated How much water can our hydrogel hold? For the purpose of this experiment, we used the following equipment:
We started by cutting out 10x10cm cloth sample to check its absorption:
Our cloth sample absorbed on average 33 ml of water.
Then, we predicted how much water a hydrogel sample can hold. To check our preditions, we cut out a Pampers nappy into 10x10cm samples and saturated it with water. On average, the hydrogel sample absorbed 325.2 ml of water.
