Contractions/Implosions

In Science we have been doing an experiment involving making a can crush itself.

Aim: To observe contractions in gases.

Hypothesis: The can will IMPLODE!

Equipment: Bunsen burner, Scissor tongs, Ice cream container, Used soda can, Gauze mat.

Method:

1. Set up your bunsen burner
2. pour apox 50-60 ml of water into the can. it should be no more than 1/4 full.
3. heat the can of water until steam is escaping from the top.
4. carefully grip the can with the tongs. be sure to have a strong grip on it before lifting it off.
5. Quickly but very carefully invert the can as you plunge it into the container of cold water.
