Homework

When the Lithium first hits the water all that happens is that it begins to bubble up. Then about three seconds later it catches on fire and begins to float around in the water. Then finally after about ten seconds of floating it burns out.


This video was kind of short but this is what happened. The very second that the cesium hit the water it exploded. The explosion was cool it looked like fireworks.


In this video the second that the potassium hits the water it catches on fire and begins to move around. Now as it's moving around it appears that it is getting a purplish glare. Now it just might be the camera but I thought that it was odd.


When this video begins nothing at all is happening. Then the alcohol's color changes to yellow. Then a red liquid comes from under the bromine and spreads through the whole cup. Then it begins to bubble and it overflows. Then as all of the foam is out the bromine has been dissolved and is gone.


This video had two experiments both we have already seen but these ones had major explosions in both of them. In the first one the sodium enters the water, bubbles up and then catches fire moves around then out of nowhere makes a massive explosion out of nowhere. It was pretty awesome. Next one the potassium enters then bubbles up then as well makes a large explosion but after the first explosion your kind of expecting it.

I feel that this one was one of the dumbest experiments. Well it's not dumb it's just not that interesting to me. What happens is that a man takes some liquid nitrogen and throws it into the water. Then a thick smoke covers the pool it was put in making it look a little odd.


Now this gummy bear experiment is one of the coolest I've ever seen. First the guy as some sort of liquid in a test tube. Then he inserts the gummy bear into the test tube and then the whole test tube sets on fire. After the fire goes out the gummy bear is gone burned away by the liquid.


I thought that this experiment was also pretty cool. First the liquid is just sitting their doing nothing then this huge amount of foam comes out of nowhere and begins to overflow like crazy. One cool thing about this video is that the foam keeps changing color from white to gray and finally to a blackish color.
