This is a cool experiment that i demonstrated to my classmates : what happens is that ...........................
A small amount of water is heated in a soda can until steaming. The can is then quickly put in cool water, mouth side down. The sudden change in temp causes a sudden change in pressure, making atmospheric pressure higher than the can pressure. Thus, the can collapses under the pressure.
1. Any soda can
2. oven or Bunsen burner
3. beaker ( 250 ml - 500 ml)
4. room temperature
P.S : this is my first instructable so please rate it!
Step 1: Getting started!
first get your beaker and fill it all the way to the top ( see first picture) - a glass cup could work too!
Then fill ur can with enough water to fill the bottom ( see second picture)
