Dublin schoolchildren share ingenious water-saving experiment

Children at a city centre school showcased their ingenious water-saving experiment at the Science Blast educational fair.

The fair asks primary school children from third to sixth class to "investigate the science behind a simple question". The project is group-based and entire classes are asked to participate.

The non-competitive science fair took place yesterday. Dylan Farsaci, a fifth class student of Canal Way Educate Together National School in the Liberties, spoke to Dublin Live about their experiment.

The 11-year-old said: "At the start, our class just wanted to see how much water we were using.

"So we basically got one tub of water in each sink in our classroom, and they would fill up when we used the tap. Twice a day, we would measure how much water there was, and then we would measure how much water was in our glasses or cups or water bottles.

"Then we would refill them and could say, we used this much. And then we measured how much water is used per toilet flush.

"When we measured how much that was, we came up with the idea that we should reuse the hand washing water to flush the toilet."

He added: "So we got bottles and filled them up with our hand washing water. Once those were filled, someone would use the toilet. Then after doing their business, they'd hold up the ballcok in the cistern and flush the toilet and shout, 'FBI, open up!'

"Then while they held up the ballcock switch, someone would pick the door with some scissors to unlock it, someone else would hold the door and then some people would dump the water tubs into the cistern. That way we would save water.

"So that's our experiment, to save water and see how much water we use. We started thinking about this project because we were learning about Qatar because of the World Cup, and we found out they basically have no water.

"So we came up with this experiment to learn how much water we use and how we can save water. We also coded some games to go along with the project, but that's not really part of the experiment."
