Sometimes when I am reaching in to get ice from our freezer, it sticks to my hands and makes our kids laugh. I decided to take this concept and do a simple science experiment so they could see why the ice sticks.
- 2 or more Cups of ice
- 3 bowls big enough for a child’s hand to fit inside
- Warm water
- Cold Water
Fill one bowl with ice and cold water. Fill the second bowl with only ice. It doesn’t need to be a full bowl. One or two cups will do. Add warm water to the third bowl. This experiment can be done in groups where each child gets a chance to participate. Have the child who is participating place one hand in the bowl of ice water and keep it there several seconds until cold. Then have the child place his or her hand in the bowl of ice. The ice will stick to the skin like magic when the child’s hand is raised out of the bowl. Then, have the child place a hand in the warm water and then in the ice. It will not stick. Discuss how the temperature of the water on their hands causes the ice to freeze to their hand or simply stay in the bowl.
It is a surprising and interesting sensory experience when the ice sticks to their hands. The warm water feels nice on their hands after the ice that is stuck comes off. Then, the ‘magic’ no longer works as the water on their hands is too warm for the ice to stick.
