Imploding Can

Today we did another experiment, this one is called " Imploding Can ". You just need to follow some easy steps and get some equipment you can find around your house. This experiment was really fun, and we're in a group of 5 people since there are only 4 cans, we needed to sensible of the fact that everyone needs to do it and get to experience it. I would probably do another experiment by myself, doing this. 

Hypothesis: The can will collapse instantaneously, instead of exploding outside but this explodes inside. 

Equipment :

- You need a tripod 

- Then you also need a bunsen burner 

- A heat mat 

- Also a gauze mat 

- Lastly the most important thing a can 

-  A container and some water.

Steps :
- Get everything you need like the equipment, but make sure you also get some safety things such as safety glasses and may some gloves if only needed. Set up everything, before you start the experiment. Also before you put the can above the tripod, put a little bit of water about 10-15 ml then you can start it.

- The last step, get scissor tongs and pick up the can since it will be hot. We don't want our hands to be burnt by the pressure. Then get a container and put water, then dip it and see what will happen and watch carefully. 

Results :

So when we heated the can, it will be caused to boil. So the vapor from the boiling water will push out some air out of the can. When the can was full of water vapor, you quickly cooled it by inverting it in water. Cooling the can led the water vapor to condense, resulting in a partial vacuum. Because of the incredibly low pressure of the partial vacuum within the can, the pressure of the air outside the can was able to crush it. When the pressure outside exceeds the pressure within, the can is crushed because the pressure differential is higher than the can's ability to resist. With your palm, you can smash an open aluminum can. When you compress the can, the pressure outside exceeds the pressure within. If you press the can hard enough, it will collapse. So actually when we were doing this we have a bit of a problem at first we thought that it wouldn't work since the third first try it was a fail. Then I thought of watching some videos that are related to this, I saw that there's a very important thing you needed to do to make this thing work. We'll use the tongs to pull the can off the stove, turn it upside down, and plunge the can's mouth into the bowl of water. With the tongs, get a solid grip on the can at the bottom and hold the tongs in the palm-up position. Lift the can from the stove, turn it upside down, and plunge it into the cool water in one fast move. That was the most important thing you needed to remember when you're going to do this experiment.

Conclusion: This motion is comparable to drinking via a straw. We claim we're "sucking" drink up via the straw, but we're not. Outside air pressure is pushing down on the liquid's surface. The force of the outside air pressing down on the surface of the water is higher than the force within the can, and the water is forced up into the can. Even though there's a lot of fail attempts we still tried until we succeed with this experiment.
