ASU Chemistry Lab

Today i went on a field trip to the ASU chemistry lab. I enjoyed the trip very much and learned a lot. Everyone who instructed me during the tour of the lab did a great job. Here is a picture of the DLC8 watching Gary, (a scientist at ASU), teach us about how liquid nitrogen can deflate a balloon because the freezing cold temperature of the liquid nitrogen causes the air inside the balloon to condense and shrink the balloon.

Here is a few other pics of what this liquid nitrogen-balloon experiment looks like:

While at ASU I got to witness a glass blower at work. She was very talented and skilled at what she does. She makes all of the custom glass wear that you use when experimenting in science. She has a blow torch which she uses to shape the glass, and she has to wear special glasses so that she can see the glass as she forms it. the end product she created for us was a swan, and it was beautiful!

 We also learned about air pressure with Tim (featured below). he performed multiple tests with a tube that sucks out all of the air from an object. He crushed a can by removing the air that filled the space inside. This resulted in a crushed can because the space that the air filled had to be filled with something else, the can itself. He also used a plastic soda bottle and crushed that. 

Another one of the highlights of this field trip was when we visited a professor who worked with high voltage and electrical currents. He literally "shocked" us with 50,000 volts of electricity! This was a great experience because I felt all tingly, and watching other peoples reactions made me laugh :D

Overall, the field trip to ASU was much better than a normal day at school, because I learned a lot about chemistry.
