METHOD,
1. Set up the 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...
3. Heat the can of water until steam is seen escaping from the top... Carefully grip the can with the scissor tongs. Ensure you have a firm hold of the can before lifting it off the glaze mat...
5. Quick;y, but very carefully, invert the can as you plunge it into a container of water...
Observation, We use a clean can full 1/4 full of water and we heated the water until it started to steam from the top of the can and using scissor tongs we picked up the can and fastly dipped the tip of the can into the cold water and the can implode because of the sudden change of temp...
The can implodes because when the can is plunged into cold water, the water vapour condenses leaving the pressure inside the can much less than the outside. As the water boils the molecules bouncing off the inside of the can creating a force pressing outwards. The pressure of the atmosphere pressing inwards.
