How to deliver parcels more sustainable? Children from 'group 8' of primary school 'De Springbok' tackled this issue during a creative morning at NLO. The children had to come up with a solution to make parcel delivery more sustainable. Ideas ranged from a cannon that shoots off parcels within 30 minutes of ordering, to drones with eco-friendly cars and personal delivery robots. In the end, the solar-powered bamboo bike won the prize for best invention. The children enjoyed the day and went home with a goodie bag and a certificate of their invention. Thanks to NL Cares for organising a fun educational morning.
