In search of his medium-sized bear, Ryan gets to the galaxy through the telescope, followed by guilt-ridden Stella, his older sister. We meet a colourful medley of characters, have a sing and dance, experience the sentiments of the storybook genre all whilst learning some rudimentary astrophysics.

Twinkle Twonkle sets out to explain the creation of our universe and the origin of the stars – the big bang – to the 4+ demographic. Associated with The Royal Society, the UK’s national academy of science, this is part of celebrations for its 350th anniversary.

Most importantly, the kids were kept engaged during most of the 50 minutes. Nursery rhyme lines were used as the characters’ walkie-talkie code to spark off some audience participation while everyone got seated, from which point a sort of magical intrigue was set. Nothing will come as a great surprise and at points I felt the plot dragged a bit but the play has all the components of a good children’s story rendered delightfully midst a humble yet alluring set.
