Today in school Mr. Curtin picked a few people to help him try out the nappy experiment. The first thing we did was we filled a nappy with water. After the nappy had absorbed all the water we ripped the nappy open. Inside the nappy is a thing called Hydrogels. Hydrogel looks very like snow or crystals. We then began to empty all the hydrogel into a small container.
Once all the hydrogel had been emptied into the containers we brought them down to the staffroom where we put them in the fridge for an hour.
After an hour, Mr.Curtin picked 9 people who would plant suttons. We were put in pairs and each pair got two pots. In one pot we mixed the soil with the hydrogel and planted the seeds. The hydrogel helps the plant last longer with less watering. In the other pot we put small pieces of cut up banana skin around the top of the soil. We then planted some more seeds in that pot. Now we are going to keep and eye on the pot and see which works better the hydrogel or the homemade banana fertilizer! We will keep you updated with our results:)
