Four teams of pupils from Wirral Grammar School for Girls are amongst the 40 finalists of the Amazon Longitude Explorer Prize People's Choice Award.

Teams Sigma, Delta, Bigas Amica and LiveAir are counting on your votes to become the public’s favourite idea and win the £5,000 prize.

The competition challenges young inventors to create, test and develop their own technology invention.

Headteacher of Wirral Grammar School for Girls, Elaine Cogan, said: “I am extremely proud of our girls. They have worked incredibly hard over the last six months on their projects, developing a wide variety of skills along the way.

“The dedication they have shown working together during a difficult year demonstrates the drive and resilience of a Wirral Girl."

Meet the teams and their inventions

Team Sigma: Arwa Fathy (16) and Kathryn James (13).

The pair have worked together to develop the idea of ‘Sanasniper.’ This is a protective phone case with a built-in refillable hand sanitiser and infrared thermometer. It comes with an app that provides its users with daily notifications, reminding them to sanitise their hands and take their temperature once a day.

Team Bigas Amica: Nila Heartin (14), Lucky Parmar (14), Yan Chen (14), Hannah McKay (12) and Beatrice Bartram (13).

Team LiveAir: Nicola Palka (15), Niamh Stephenson (15), Ruby Noon (15) and Pratharna Vinoth (15).
