Designed to challenge boys and girls to discover liquid capacity (either ml or fl.oz) on their own, the snail-shaped Scrunch Water Meter could work just as well in the bathroom (it will stick to the side of the bathtub) or in the garden to measure the rain, or on the beach simply playing with water, or in the kitchen helping with some cooking, enormously versatile.

The numbers are embossed on the inside of the snail's shell appearing up and down.
