Color Changing Fish Hot Water Bottle

Animal activists will probably scream blue murder when they come across the Color Changing Fish Hot Water Bottle, but this £9.99 purchase will not feature live fish inside, but fake ones that will change their shades depending on the temperature of the water within. No longer do you need to make a guess on whether the hot water bottle will scald your fingers or not, as these plastic swimmers will turn white if the water is too hot, or purple if the water has turned extremely cold within. Their natural color would be pink, so you can let your eyes do the judging from there. An interesting purchase for the safety-conscious who do not want to end up with unnecessary burns. Bear in mind that it is recommended to use hot water with the Color Changing Fish Hot Water Bottle, and not boiling water.
