Crushed Can Experiment Illustrates Air Pressure and Temperature Changes
Aluminum Can Compression Test or Can-Crushing Experimentation
Learn about the fascinating world of physics with a simple yet captivating experiment, the Crushed Can Experiment. This engaging demonstration allows children to explore the principles of air pressure and temperature changes, perfect for students in grades 3-6.
The Crushed Can Experiment is an easy and thrilling way to understand how the cooling of a heated can filled with a small amount of water creates a vacuum. The vacuum is then followed by a surge of external air pressure, which crushes the can.
To perform this experiment, you will need an empty aluminum can, water, a heat source such as a stove burner, tongs, and a bowl of ice water. First, prepare a bowl with ice and water. Then, place two tablespoons of water in an empty aluminum can and set it on a stove burner or over a flame until the water inside turns to steam. Using an oven mitt or tongs, carefully remove the steaming can from the heat source, and quickly flip it upside down into the bowl of cold water. Observe as the can implodes due to the external air pressure.
The science behind this impressive demonstration involves a phase change, where the liquid water in the can turns into steam, and then condenses back into a liquid upon contact with cold water. This rapid transition in state generates a decrease in internal air pressure within the can, making it susceptible to external air pressure, which ultimately crushes the can.
This experiment offers a fun and practical way to explore various physical science topics, including states of matter, gas laws, and forces. By understanding the principles of air pressure, phase changes, and physical changes, students can develop a solid foundation for further studies in physics.
For additional science experiments that explore the concept of air pressure and temperature changes, try the Balloon Rocket, Balloon in a Jar Experiment, Rising Water Experiment, Tea Bag Rocket, and Egg in a Bottle Experiment. Each of these experiments offers a unique and interactive way to learn about these fascinating principles.
