Science Experiment

The Imploding can

Aim: To observe contraction in gases

Equipment: Aluminum can, Scissors tongs, Bunsen burner, heatproof mat, tripod, gauze mat, an open container of water.

Method:

1.Set up bunsen burner underneath a tripod and gauze mat
2. Pour approximately 50-60 ml of water into your can it should be no more than 1/4 full.
3. Heat the can of water until steam is seen escaping from the top.
4. Carefully grip the can with scissors tongsEnsure you have a firm hold of the can before lifting it off the gauze mat.
5.  Quickly, but very carefully, invert the can as you plunge it into a container of water.

Observation: As we put the heated can into the water upside down. It made a big bang as soon as it hit the water. But as it hit the water it scrunched up like somebody had stomped on it or like somebody scrunching a piece of paper.
