- Ice cubes
- Tap water
Will your hands be able to feel the difference in the water temperature?
- Fill one bowl with water s hot as you can comfortably rest your hand in it.
- Fill another bowl with cold water and add ice to it.
- Fill the last bowl with lukewarm water
- Place on hand in the bowl of hot water while you put the other hand in the bowl of cold water. Do this simultaneously. How do your hands feel?
- Next, put both hands in the bowl of lukewarm water. Now how do your hands feel?
