The Derby Computer Museum is one of over 200 attractions around the UK participating in the Blue Peter Badge Attraction Scheme.
To gain free entry, each child must have a badge and valid badge card, and be accompanied by a full paying adult.
This offer does not apply to school, community or group bookings, and cannot be used to gain entry to pop-up events at other locations or on special event days.
Before you visit any of the attractions, grab a grown-up and read the Blue Peter Terms and Conditions.
