Building Sandcastles Just Got A Whole Lot More Competitive

If you've been thinking of going to the beach and making a giant iPhone sandcastle, then you might want to pick up a Castle King kit before you leave.  Based on the equipment used by professional sand sculptors, the non-stick sheath uses sand's inherent water-retention balance to create big, carvable chunks.

Excess water drains away at the bottom and leaves a pillar of solid sand that can be shaped, hollowed out or – in the case of your iPhone homage – given a multi-touch interface and Google Maps.

It's available now for £17.90 ($36)
