Can experiment (Science)

In Science today we did a small experiment... PUTTING A CAN OVER HOT FRIE THEN PUTTING IT IN WATER. Well doesn't seem like much but it was fun

Aim: To observe contraction in gases

Method: (1) Set up the bunsen burner
(2) Pour about 50-20 ML of water into your can. It should be no  more than 1/4 full
(3) heat the can of water above the flame of the bunsen until steam is seen escaping from the top, then carefully grip the can with the scissor tongs while making sure you have a firm grip on the can, then left it off the gauze mat
(4) Quickly but carefully, invert the can as you plunge it into a container of water

Hypothesis: Maybe it would explode like. explode explode.

(It didn't fully Explore... it just made it's self smaller as in when you crush a can with your hands)

Equipment: Can (With water) Ice cream container (With water) Bunsen burner. Scissor Tongs

We had proceeded to put our equipment up, we filled the container up with water to the line, and stuck a bit of water in the can, before lighting the bunsen burner with a lighter and turning it to the blue flame and then holding the can over the fire with the scissor tongs.

We waited for a bolling sound before lifting the can off of the fire, and then quickly into the container of water, to then instantly hear a crunching sound from the can.
