The event, which replaced the usual fireworks display, was organised by the PTA, who provided a full bar and organised foodie vans, ice cream and candy floss.
The festival at the Welwyn school was opened with the WGC Brass Band, followed by dancers from the DH Dance Academy.
Entertainer Ray Bubbles amazed parents and children alike with sight of hundreds of colourful giant bubbles being released whilst the band played Happy Birthday.
Later in the day, Ray broke a Guinness World Record by bouncing a bubble between him and his son 20 times. The evidence has been sent to Guinness for verification. Ray concluded his performance by putting some children into their own bubbles!
Chair of the PTA Brian Hedges said: "The festival was an outstanding success with hundreds of Sherrardswood parents and students attending - it also raised some significant funds for PTA projects. Plans are underway for a repeat festival next year along the same lines."
