cynet (USA) Changing Color Drink (for parties, just to look cool) Problem is would it be safe to drink such a drink. If not just reverse the effect. Have a liquid inside two thin layers of glass inside the glass and the temperature (of the drink) inside the glass changes the outside color. Have a light imbeded in the bottom of the cup to enhance the effect. Reward: One cool drink, and a girl to dance the night away. |
