As the audience enters, two performers (Shane Shambu and Louise Gibbons) are quietly and curiously catching ‘drips’ from the ceiling that echo around the room. This instantly captures the babies’ attention and allows everyone to get settled with a minimum of fuss.

Towards the end of the roughly half-hour performance, the performers start directly involving the audience, first by tipping sponges on their heads, to everyone’s delight, and then by lifting individual babies onto the stage for their moment in the spotlight. This is a heart-stopping moment for any parent present, unsure as to how their child will respond. But the performers seem deeply attuned to reactions of the babies, being as gentle or energetic as required. The few babies who did cry were instantly reunited with their parents with no further fuss, whilst older or less nervous babies were swung around and entertained with a sponge.

This audience interaction soon segues smoothly into a twenty minute play session, with everyone invited onto the stage to play with the mountain of sponges. Throughout this, Shane and Louise continue to engage with the audience, encouraging tower-building, sponge throwing and sitting within the giant plastic buckets. No-one wants to leave – it seems they would stay for hours if they could – but the end is cleverly signalled with a couple of collective “sponge explosions” followed by a sorting-and-tidying of sponges into their buckets.
