A rubber band, metal links and gravity... a new way to apply eyedrops

A ‘directed eyedropper’ was invented by Limerick students Shannon Naughton, Sarah O’Grady and Aoife Larkin.

APPLYING EYEDROPS CAN be very fiddly, so three Limerick students have invented a new style of eyedropper to make things easier.

The ‘directed eyedropper’ was created by Shannon Naughton, Sarah O’Grady and Aoife Larkin of Desmond College in Limerick, a school that has consistently sent students to the BT Young Scientist and Technology Exhibition over the past 50 years.

The prototype was created using metal links, a rubber band, and circles of piping.

Here’s Naughton explaining more:
