Glowfish lights up your bath time

Taking a bath is relaxing, but having the help of scented candles and a soothing light definitely helps enhances the atmosphere. The Glowfish comes in the form of a giant goldfish, and lights up automatically whenever it is placed into a bath. Whenever the Glowfish comes into contact with water, it will start to entertain you with a color phasing light show. The internal battery is capable of up to 38 hours of relaxing light, but I have no idea whether these can be replaced or not or do we need to purchase a brand new Glowfish. The Glowfish measures 19cm x 8cm x 7cm and retails for £6.95 each.
