MAGIC SHOW

MAGIC SHOW
Today we had a matter magic show in science. Its was great, there was so many kids, so many interesting experiments for the kids and for us to see, it turned out to be great. My partner was Elena, and we had a very great and interesting trick. What we did is put a little water in a bowl, and then we put a candle on it and lit it. Then we would put a glass over the candle and what would happen is that the water would be sucked up in the glass cup because of the air pressure. The height would decrease and so the air pressure would suck the water in the cup.  Our trick worked very well, but at one point the candle would not light because it was wet, so we had to dry it. All the little kids thought it was cool and amazing. And so did my class mates.

Changing Phases

While I was doing this I realize that if you put the lid at the same level for each of them, they are all going to explode, but only if you add pressure, or you can add molecules, and by that, you are adding pressure between the molecules. I also realized that the lower i put the lid down there will be less volume, but more pressure, and if you put the lid higher, then there will be more volume, but less pressure because the particles are moving slower.  I also realized that the less pressure something has, the slower it will explode.

If you also add a lot of height it can explode. I also realized that once the particles are spread out, then when you take away heat, you are taking away energy, so they start forming one or little group. But once they are as a solid, and then I add height od add energy, then the particles will be moving faster and they will go everywhere because I am adding energy and pressure, so it will have more volume.
