How Big Are Your Lungs?
Science is never boring at Senior Boys as demonstrated by class 7A when they measured lung volume.
To do their experiment the boys used a plastic bottle with some hose pipe, washing up bowls and water! As they breathed out, the volume of water pushed out of the bottle was equal to how much air their lungs could hold.
We can’t confirm the results but there was a lot of ‘hot’ air!
