Videos: 


 1. This is one example of what happens when two different substances mix together. Some react and some don't react at all, but in this case we have a large reaction. The first reaction is the alcohol turns yellow and then as bromine dissolves, it turns red. 
2. Water is one of the substances that cant get almost any element onto fire, and that's what makes this video unique. When lithium is placed into a tray of water, flames come out of the lithium.
3. Another video that has a mix of water and cesium. Cesium when mixed with water it reacts somewhat like fireworks. 
4 Like other substances that are mixed with water, this one also gets lit on fire. This is what happens when the two potassium and water are mixed.
 5. When sodium and potassium are mixed they can create an extreme explosion that can be a hazard if not following the lab safety rules.
6. In this video we see how the liquid nitrogen spreads over the pool like a big blanket. This shows another reaction, liquid nitrogen and water in this case were not mixed...they cannot be. It will stay separated.
7. This one shows how two different substances can react. Not many substances react similarly, this substance fizzed up and made the beaker overflow. This a very unique project there are not many reactions like this.
8. Another reaction of how it explodes. I think that this explosion was not created because the gummy bears color or anything else, but the sugar and theother substance put in created this explosion.
9. It is not clearly explained what these substances are and why this happens when they are mixed.

    Wow, I think this video is really cool. We should maybe try it in class. Instant Ice, I wish we could do that as a lab.

    This video is great, I never knew you can make instant hot ice so easily. I agree that we should try it in school, it would be awesome.
